Dinosaurs in New Jersey: Edelman Fossil Park & Museum in Mantua to offer prehistoric fun.

Yahoo21-03-2025

MANTUA — The address says it all for a new attraction here: 66 Million Mosasaur Way.
That's the home of the Edelman Fossil Park & Museum, where a deep quarry offers access to the sea floor — and dinosaur remnants — from 66 million ago. The museum's eye-catching displays include the 30-foot-long skeleton of a mosasaur, an aquatic reptile with chainsaw jaws.
The $75-million complex, set to open March 29, is primed to allow a largely youthful audience to gawk at prehistoric beasts in the museum and, from May through October, to dig for fossils in the quarry.
Not a bare-bones approach: Fossil park and museum open in South Jersey
'What we've accomplished here will have impact well beyond Gloucester County,' Rowan President Ali Houshmand said at a ribbon-cutting March 20. "Soon enough, school buses full of children will experience this amazing facility.'
New Jersey Gov. Phil Murphy, who also attended the ribbon-cutting, called this a day for the history books.
"It will attract people from all across the country," Murphy said.
The museum's own history dates to 2003, when paleontologist Ken Lacovara, then at Drexel University in Philadelphia, learned of the Mantua quarry and its rare window into the past.
The quarry, also called a marl pit, was owned by Inversand Co., a Clayton firm that mined clay.
Over the next few years, Lacovara worked with Michelle Bruner, Mantua's director of economic development, to build grassroots support for the fossil site. That included "community dig days" at the still-privately owned quarry off an access road near the intersection of southbound Route 55 and Woodbury-Glassboro Road.
"I was hoping that maybe 75 people would show up on a Saturday morning to dig fossils with us," Lacovara said of the first community event. "(Approximately) 1,600 people showed up."
He also reached out to Rowan administrators to promote the quarry's educational value and to save the site from commercial development.
Rowan bought the 123-acre property for approximately $2 million, and Lacovara became the first dean of its School of Earth and Environment in 2016. He's now the museum's executive director.
"Currently, about 4 acres of the former marl quarry are dedicated to paleontological research and fewer than 300 square meters of it have been fully processed,"a Rowan representative said.
Areas of active research by Rowan faculty and staff are separated from public dig areas.
The quarry already has yielded more than 100,000 fossils from more than 100 extinct species. It was under the ocean when an asteroid strike wiped out most dinosaurs back in the late Cretaceous period, so most fossils have come from marine life including turtles, crocodiles and a mosasaur.
But Rowan researchers have also found fossils from land-dwelling dinosaurs that drifted away from a coastline that was then near modern-day Philadelphia.
The museum is expected to attract families and school groups with dinosaur sculptures, live animal exhibits and interactive displays. It also has a dinosaur-themed playground.
Ric and Jean Edelman, Rowan alumni graduates and philanthropists, donated $25 million to the project.
"There's nothing better for children to get excited about science than the stars and the dinosaurs,' said Ric Edelman, who with his wife has also funded a planetarium on Rowan's Glassboro campus.
General admission ticket prices for the museum are $24 for children ages 3 to 12, and $29 for older visitors. The 75-minute Quarry Dig Experience is $25 with museum admission, or $40 on its own.
'For all the memories we're going to create, it just fills our hearts,' Jean Edelman said.

‘The missing link': New early tyrannosaur species discovered by Calgary researchers

CALGARY - Scientists from the University of Calgary have discovered a new dinosaur specimen that they say appears to be the 'missing link' in the evolution of tyrannosaurs. The specimen was originally discovered in Mongolia's Gobi Desert over 50 years ago in the 1970s. But its significance wasn't recognized until Darla Zelenitsky, an associate professor in the university's faculty of science, sent graduate student Jared Voris to Mongolia on a research trip. 'He was there a couple of years ago on this research trip and looked at the fossil and texted me (that) he thought it was a new species. I was like, 'yay,'' Zelenitsky told The Canadian Press. 'I said, 'This is good, but we don't want to jump the gun on this.' It turned out it (was) a new species.' The species, Khankhuuluu mongoliensis — meaning 'Dragon Prince' or 'Prince of Dragons of Mongolia' — is believed to have crossed via a land bridge from Siberia to Alaska roughly 85 million years ago. Zelenitsky said it appears to sit on the evolutionary scale between smaller tyrannosauroids and tyrannosaurs. 'It's the missing link between smaller tyrannosauroids and the large predatory tyrannosaurs,' she said. 'This missing link was around 750 kilograms. Its ancestors were a couple of hundred kilograms and just tiny, but then when you get to tyrannosaurs proper, they were over a thousand kilograms, up to estimates of 5,000 kilograms.' The findings were published Wednesday in the British weekly scientific journal 'Nature.' 'It's really exciting to be involved in a discovery of something that's been sitting in a drawer for 50 years. But it's even more exciting when it's a PhD student that makes that discovery,' Zelenitsky added. 'This discovery forced us to look at the family tree of tyrannosaurs in a very different light. It ended up with us rewriting the family history of tyrannosaurs.' The arrival of Khankhuuluu or a similar species after moving from Asia to North America may have been the result of following their prey to a new location, said Zelenitsky. 'It's possible that there weren't many tyrannosaur type predators so it's possible they were able to take over that niche in North America and moved to the top of the food chain,' she said. 'Tyrannosaurs were in the right place at the right time. It allowed them to diversity and evolve a large body size, ultimately becoming the massive apex predator that terrorized North America and Asia during the late Cretaceous period.' Zelenitsky said the evolution to the tyrannosaur happened rapidly, geologically speaking, and probably took a few million years. She has co-authored over 50 different publications during her career and was part of a team that first found evidence of feathered dinosaurs in North America.

Ancient T. rex ancestor discovered: Khankhuuluu, ‘prince of dragons'

A new species of early tyrannosaur, dubbed the 'prince of dragons,' has been discovered lurking in a collection of fossils first excavated in Mongolia in the early 1970s, scientists said Wednesday in the journal Nature. Khankhuuluu mongoliensis — its scientific name — is an evolutionary ancestor of the most famous tyrannosaur, the 'tyrant lizard king,' T. rex. With their bone-crushing bites and spindly little arms, large tyrannosaurs (scientifically known as 'eutyrannosaurians') are the celebrities of the dinosaur world. But they started off as small-bodied tyrannosauroids some 150 million years ago in the Jurassic period. It wasn't until the late Cretaceous that they began evolving into the giants that ignite people's imaginations. Their precise evolutionary origins, however, have long been murky. A critical swath of the family tree is blank. Khankhuuluu, known from two partial skeletons in fossil collections at the Institute of Paleontology in Mongolia, helps fill in this gap — a transitional 86 million-year-old species that represents the closest known ancestor to the famed late tyrannosaurs. Previously, it had been described as an alectrosaurus, another early tyrannosaur. Asked for a modern-day comparison, University of Calgary graduate student Jared Voris, who led the work, said to imagine a large, predatory horse. 'What makes them so important is their age,' said Stephen Brusatte, a paleontologist at the University of Edinburgh who was not involved in the study. 'They are about 86 million years old, a good 20 million years older than T. rex. It has been a frustrating gap in the record.' Voris was on a research trip in Mongolia in 2023 when he sent a text halfway across the world to his adviser, Darla Zelenitsky, an associate professor of paleontology. He told her that he thought some of the fossils he had examined in a museum collection were actually a new species. Those specimens had been classified for decades as alectrosaurus, 'an enigmatic and poorly represented tyrannosauroid species,' Zelenitsky and Voris wrote in their study. What leaped out to Voris initially was that the snout bone was hollow, a clear sign that this was an early ancestor of the tyrannosaur family. It was the first of what would come to be dozens of features that suggested this creature was something new. Zelenitsky, a paleontologist at the University of Calgary, said she was excited but cautioned Voris to take his time. Some bones were sent to Japan, where the research team was able to conduct CT scans to study them in greater detail. The scientists also traveled to the American Museum of Natural History in New York to study alectrosaurus fossils to make sure the animals they were researching were distinct. 'There's no doubt this is a new species,' Zelenitsky said. 'There's also no doubt that it's the ancestor to these large apex predator tyrannosaurs.' The new study reveals an intermediate form — a slender, relatively flat-snouted creature. Other tyrannosaur experts said it was good to see these specimens reexamined with modern techniques and understanding. Thomas R. Holtz Jr., a vertebrate paleontologist at the University of Maryland, recalled that in the 1980s, the find in Mongolia was relatively famous within the small community of tyrannosaur specialists. He was the envy of colleagues back then, because he had been able to hunt down a blurry microfiche of the paper, published in an obscure Mongolian geologic journal in the 1970s. 'It helps fill in a gap in time and in the evolutionary tree,' Holtz said. Khankhuuluu is part of a gold rush in discoveries that are filling in more chapters of tyrannosaur evolution. Over the past 15 years, there has been an explosion in discoveries of tyrannosaur species, said Joseph Sertich, a vertebrate paleontologist with the Smithsonian Tropical Research Institute. Sometimes, new species come to light by dusting off old fossils and finding ones that were misclassified in museum collections, as in the new study. Other times, scientists dig up new bones. Voris and Zelenitsky paint a picture of species evolution and migration as tyrannosaurs dispersed between Asia and North America over millions of years. Khankhuuluu, or another closely related species, left Asia and moved into North America, giving rise to tyrannosaurs there around 85 million years ago. Several million years later, a migration back to Asia resulted in two new branches of the tyrannosaur family tree: the giants on one branch and the 'Pinocchio rexes' — smaller dinosaurs with long, slender snouts — on the other. And at the very end of tyrannosaur evolution, one of the giants migrated back to North America, giving rise to T. rex. Sertich drew the analogy to big cats, where many species can live alongside one another — leopards, lions or tigers coexisting as predators in the ecosystem. 'The patterns of evolution we are uncovering are revealing a complex story of evolution that goes far beyond tyrant dinosaurs and has bearing on the origins of the modern ecosystems of the Northern Hemisphere,' Sertich said. 'Ultimately, this paper is exploring the ancient connections between North America and Asia, two continents that have shared species, including humans, for the past 90 million years.'

Paleontologists dig through fossilized dino guts to see what's inside

Nothing quite fits the moniker 'gentle giant' more than sauropods. These gargantuan dinosaurs could reach up to 123 feet long and weigh up to seven tons. Sauropods have long been believed to be herbivores, munching on leaves during the Jurassic and Cretaceous periods. Now, for the first time, a team of paleontologists have studied the abdomen of a sauropod with its gut contents still intact that lived roughly 94 to 101 million years ago. The finding confirms that they were in fact herbivores–and did not really chew their food. Instead, sauropods relied on gut microbes to break down its food. The findings are detailed in a study published June 9 in the Cell Press journal Current Biology. 'No genuine sauropod gut contents had ever been found anywhere before, despite sauropods being known from fossils found on every continent and despite the group being known to span at least 130 million years of time,' Stephen Poropat, a study co-author and paleontologist at Curtin University in Australia, said in a statement. 'This finding confirms several hypotheses about the sauropod diet that had been made based on studies of their anatomy and comparisons with modern-day animals.' Fossilized dinosaur bones can only tell us so much about these extinct animals. Paleontologists can use trackways and footprints to learn about their movement and preserved gut contents called cololites to put together what their diets may have looked like. Understanding the diet is critical for understanding their biology and the role they played in ancient ecosystems, but very few dinosaur fossils have been found with cololites. These are gut contents that have yet to become poop–or coprolites. In particular, sauropod cololites have remained elusive. With their gargantuan sizes, these dinosaurs may have been the most ecologically impactful terrestrial herbivores on the planet during the Jurassic and Cretaceous periods. With this lack of direct dietary evidence, the specifics of sauropod herbivory—including the plants that they ate—have mostly been theorized based largely on tooth wear, jaw shape and size, and neck length. But that changed in the summer of 2017. Staff and volunteers at the Australian Age of Dinosaurs Museum of Natural History were excavating a relatively complete subadult sauropod skeleton. This particular Diamantinasaurus matildae specimen lived during the mid-Cretaceous period and was uncovered in the Winton Formation of Queensland, Australia. The team noticed an unusual, fractured rock layer that appeared to contain the sauropod's cololite with well-preserved plant fossils. The team analyzed the plant specimens within the cololite and found that sauropods likely only engaged in minimal oral processing of their food. Instead of chewing, their gut microbiota would ferment the plants to digest it. The cololite had a wide variety of plants, including foliage from conifers (cone-bearing seed plants), seed-fern fruiting bodies (plant structures that hold seeds), and leaves from angiosperms (flowering plants). From this, it looks like Diamantinasaurus was an indiscriminate, bulk feeder. 'The plants within show evidence of having been severed, possibly bitten, but have not been chewed, supporting the hypothesis of bulk feeding in sauropods,' said Poropat. The team also found chemical biomarkers of both angiosperms and gymnosperms—a group of woody, seed-producing plants that include conifers. [ Related: The mystery of why some dinosaurs got so enormous. ] 'This implies that at least some sauropods were not selective feeders, instead eating whatever plants they could reach and safely process,' Poropat said. 'These findings largely corroborate past ideas regarding the enormous influence that sauropods must have had on ecosystems worldwide during the Mesozoic Era.' Although it was not unexpected that the gut contents provided support for sauropod herbivory and bulk feeding, Poropat was surprised to find angiosperms in the dinosaur's gut. 'Angiosperms became approximately as diverse as conifers in Australia around 100 to 95 million years ago, when this sauropod was alive,' he says. 'This suggests that sauropods had successfully adapted to eat flowering plants within 40 million years of the first evidence of the presence of these plants in the fossil record.' Based on these findings, the team suggests that Diamantinasaurus likely fed on both low- and high-growing plants, at least before adulthood. As hatchlings, sauropods would have only been able to access food that was close to the ground. As they grew (and grew and grew), their viable food options also expanded. Additionally, the prevalence of small shoots, bracts, and seed pods in the cololite implies that subadult Diamantinasaurus likely targeted new growth portions of conifers and seed ferns. These portions of the plant are easier to digest. According to the authors, the strategy of indiscriminate bulk feeding likely served sauropods well for 130 million years. However, as with most studies, there are some important caveats and limitations. 'The primary limitation of this study is that the sauropod gut contents we describe constitute a single data point,' Poropat explained. 'These gut contents only tell us about the last meal or several meals of a single subadult sauropod individual.' We also don't know how the seasons affected diet, or if the plants preserved in this specific sauropod represent a diet typical of a healthy sauropod or a more stressed one. The specimen is also a subabult, which could mean that younger sauropods had this more than adults did. Despite the limitations, it offers an exciting look inside the stomachs of some of the largest creatures to ever live.
