Denver dinosaur museum makes ‘historically thrilling' discovery under its own parking lot
The partial-bone fossil was found 763 feet below the lot during a geothermal test drilling project in January, according to the museum.
'This is a scientifically and historically thrilling find for both the Museum and the larger Denver community,' said James Hagadorn, the curator of geology at the DMNS, in a statement.
The museum said the fossil is the deepest and oldest dinosaur fossil ever found within Denver city limits.

'This fossil comes from an era just before the mass extinction that wiped out the dinosaurs, and it offers a rare window into the ecosystem that once existed right beneath modern-day Denver,' Hagadorn said.
The fossil bone has been identified as a vertebrae of an herbivorous dinosaur, according to the museum, which said the bone occurs in Late Cretaceous rocks that are dated to approximately 67.5 million years ago.
Patrick O'Connor, director of Earth & Space Science at the DMNS, was part of the team that identified the bone and said it may be 'the most unusual dinosaur discovery' he had ever been a part of.
'Not only is it exceptionally rare to find any fossil as part of a drilling project, but the discovery provided an outstanding collaborative opportunity for the Museum earth sciences team to produce an article,' O'Connor said.
That article, 'Denver's deepest dinosaur,' was published in the scientific journal Rocky Mountain Geology in June. The research was led by DMNS postdoctoral scholar Dr. Holger Petermann.
'This fossil underscores the highly fossiliferous nature of the entire D1 Sequence (Denver Formation) and increases the diversity of dinosaurs known from the Denver metropolitan area,' reads an excerpt from the article's abstract.
The fossil bone is now currently on display at the DMNS in its 'Discovering Teen Rex' exhibition.

New Mexico Museum of Natural History & Science to host community celebration before temporary closure
ALBUQUERQUE, N.M. (KRQE) – The New Mexico Museum of Natural History & Science will be hosting a community 'closing celebration' on Aug. 3, one day before the museum is set to temporarily shut its doors for its first major renovation in decades. Officials said they plan to make a new entrance including rebuilding the lobby, add a new ticket booth, expand the gift shop, refresh permanent exhibition halls, replace the skylights in the atrium and Cretaceous Hall and update the main sewer line. Village of Ruidoso says its ready to welcome visitors back after devastating floods The 'Closing Celebration will take place at the museum from 11 a.m. to 4 p.m. and will feature all-ages activities including face-painting, balloon animals, and more. Vistiors will also be able to catch a free show in the Verus Research DynaTheater or the Planetarium, and get their picture taken with the roaring Bisti Beast, Bonita, on the museum's 2nd floor. The museum expects to open back up in March 2026, and plans to have a 40th anniversary celebration for the museum, which opened in 1986.

How to watch two meteor showers peak together in late July
WASHINGTON (AP) — It's almost time for summer's meteor shower duet. The Southern Delta Aquariid and the Alpha Capricornid meteor showers peak at the same time — in the early morning of July 30. Without too much interference from moonlight — the waxing moon will be only about a quarter full — the meteors should appear bright and clear in regions away from city lights. With each shower expected to produce up to a dozen visible meteors per hour under dark skies, the doubleheader means the total number of meteors 'do add up,' said Thaddeus LaCoursiere, planetarium program coordinator at the Bell Museum in St. Paul, Minnesota. 'Look for flashes of light in the night sky,' he said, adding that both are 'very nice classic meteor showers.' The Alpha Capricornids — produced by slower-moving meteors — may have tails that linger slightly longer in the sky, said Nick Moskovitz of the Lowell Observatory in Flagstaff, Arizona. Viewing of each shower lasts through August 12. What is a meteor shower? As the Earth orbits the sun, several times a year it passes through debris left by passing comets and sometimes asteroids. The source of the Delta Aquariids is debris from comet 96P/Machholz. The Alpha Capricornids stem from the comet 169P/NEAT. When these fast-moving space rocks enter Earth's atmosphere, the debris encounters new resistance from the air and becomes very hot, eventually burning up. Sometimes the surrounding air glows briefly, leaving behind a fiery tail — the end of a 'shooting star.' You don't need special equipment to see the various meteor showers that flash across annually, just a spot away from city lights. How to view a meteor shower The best time to watch a meteor shower is in the early predawn hours when the moon is low in the sky. Competing sources of light — such as a bright moon or artificial glow — are the main obstacles to a clear view of meteors. Cloudless nights when the moon wanes smallest are optimal viewing opportunities. And keep looking up, not down. Your eyes will be better adapted to spot shooting stars if you aren't checking your phone. When is the next meteor shower? The next major meteor shower, the Perseids, peaks in mid August. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Science and Educational Media Group.

Dead scientist's 'time capsule' in vault key to resurrecting Aussie species
A sprawling collection of 3,500 specimens held in the vault of an Australian museum could provide an insight into a natural world that was largely destroyed last century, and help resurrect species that have disappeared from the area. Each tiny glass vial contains a trapdoor spider, and all of them were collected by one woman. Many of the species are now locally extinct from the sprawling Wheatbelt region that surrounds Perth. Spider expert Dr Mark Harvey, who is leading a project at Western Australian Museum, to digitise the collection, describes it as a 'time capsule'. By understanding which spiders were present at any given location, scientists are able to form a picture of what the wider ecosystem once looked like before it was replaced with crops of wheat and canola, or grassy paddocks for raising livestock. For instance, the shield-backed trapdoor spider (Idiosoma nigrum) preferred to live in woodland that was fairly flat and not very dense. And this same specific type of landscape would have also been home to many of the small mammals that are now locally extinct. When the shield-backed trapdoor spider was collected in the 1950s, the species was considered abundant on the Wheatbelt. Today it survives in a few small fragments of bushland that were retained in the region. 'Once they've been lost from an area, because the native habitat is a patchwork, and no longer connected, they can't move from one place to another to recolonise,' Harvey said. 'Trapdoor spiders are very bad at that at the best of times, because the spiderlings come out of the mother's burrow, they might only walk one, two or three metres before they start their own. And that's where they spend the rest of their lives — so they don't disperse like other animals do.' Related: Major weather event prompts behavioural change in Wheatbelt wildlife A healthy ecosystem in southwest Australia has 10 to 15 species of trapdoor spider, so when researchers return to an area and only find two or three, they know localised extinctions have occurred and the landscape has been degraded. Woman watched as entire region transformed The spiders were all collected by Dr Barbara York Main, known as Australia's spider lady, who died in 2019. She was born in 1929 and grew up in the Wheatbelt, giving her a front seat to watch the dramatic change that occurred over her lifetime. The collection contains a number of species that are yet to be officially described or named by scientists. By digitising her collection, the data will become available to scientists around the world, and the general public through the Atlas of Living Australia and WA's Dandjoo statewide biodiversity data platform. In 2025, the impact of habitat destruction on native species is well-known, but several species of trapdoor spider are barely surviving the ongoing threats to their range. The Euoplos dignitas in Queensland's Brigalow Belt was only identified in 2023, and it's already endangered. It survives in a heavily fragmented 1850 square kilometre area that successive state governments have allowed to be cleared for cattle grazing and crops.

But even if de-extinction is not possible, it might be possible to help fragmented populations of spiders, that have become genetically compromised as their numbers have shrunk. 'We could use those specimens taken from when they were fairly widespread species across the landscape, look at its genetic variation, and then compare it to the modern examples we might find now. When the populations have shrunk in size, and we can see what sort of genetic variation is lacking,' Harvey said. 'We might be able to do something about it with gene splicing.'
