In the day, how big could the real monster dinosaurs get? Renowned paleontologist Ken Lacovera, best known for his discovery in 2005 of Dreadnoughtus shrani, a 65-ton, 77-million-year-old Titanosaur unearthed in Patagonia, can tell you.
Dreadnoughtus is one of the largest land animals ever to have roamed the Earth. One wonders what 1960s fictional television character Fred Flintsone would have thought had he encountered such a beast. Dread (pun intended) might be an appropriate word.
We recently caught up with Lacovera, 64, for thoughts on his 'mammoth' discovery two decades back. Following are edited excerpts from a longer conversation.
Jim Clash: What were you thinking when you first unearthed Dreadnoughtus?
Ken Lacovara: When I found a 1.9-meter [6' 3'] femur bone in the desolate badlands of Patagonia, I suspected I'd discovered a new species of colossal plant-eater. That evening, under the blazing southern stars, I stared at the first few of the 145 bones we'd eventually unearth, wondering: 'Who are you? Where did you come from? What happened to you?' And, more practically, 'How am I going to get you out of here?' Our site was accessible only by raft and horse.
Clash: What have been the implications of that find for the science of paleontology?
Lacovara: At 65 tons - nine times the mass of a T. rex - you'd think Dreadnoughtus was near the upper limit for terrestrial animals. But bone analysis revealed it was still growing fast, even at its death!
Clash: You're also a noted jazz drummer. Was there a moment when you had to choose one path over the other?
Lacovera: Yes. After a stint at the Golden Nugget in Atlantic City [New Jersey], I was offered a Broadway gig in New York. But science had already gripped me, ignited largely by Carl Sagan's 'Cosmos,' so I chose graduate school. In a cosmic bit of serendipity, years later my first expedition was funded by Ann Druyan, Sagan's widow. Music remains part of my life, though. I still carry sticks when I travel, and can usually find a spot on stage to sit in.
Clash: You recently cut ribbon on a new museum, correct?
Lacovera: Over the past two decades, I've gone on to excavate thousands of fossils in southern New Jersey of all places, opening a window on the final chapters of the dinosaur age. To share these discoveries, we have opened the Edelman Fossil Park & Museum, a carbon net-zero architectural wonder with state-of-the-art exhibits, gardens, nature trails and a quarry where visitors can dig for fossils themselves. How about that?

Conspiracies Are Real. The Theories Can Be Traps.

Scientists studying the cosmos often speculate about hypothetical forces that might explain peculiar data or results. For instance, some astronomers have suggested that our solar system has an extra planet, way beyond the demoted Pluto, whose effects explain certain other celestial movements. And modern cosmology assumes a vast invisible substance, so-called dark matter, whose hypothesized existence makes sense out of gravitational effects that would be otherwise mysterious. Conspiracy theories, lately so influential in American debates, can be understood as the political equivalent of dark-matter theories. They emerge in situations where some movement or action seems unlikely or bizarre — unless you can posit some unseen element in the story, some hidden force exerting influence. 'Something is missing from the data' is not just a researcher's reaction to a scientific mystery. It's also a citizen's response to developments that don't seem to quite make sense. Sometimes this response and the theorizing it generates are totally misguided, like a crackpot scientist who invents an extra universe when a tiny tweak of his results would make the issue go away. But sometimes there is something unseen in the story, and the mistake isn't to theorize about it; it's to lock on too quickly to a single theory, often for ideological reasons, when other solutions might work just as well. Take, for example, the case of Jeffrey Epstein, about which I remain a conspiracist, in the sense that I believe that key events and influences in his story have yet to be revealed. But the leading theories about those hidden events are heavily conditioned by ideological impulses. MAGA activists and influencers have long focused on the possibility that he ran a sex ring for wealthy men, which fits their existing narratives about child trafficking and elite perversion. Then more recently, the Trump resistance has taken up the theory that the Epstein dark matter might be directly connected to Donald Trump himself. And at the same time, part of the populist right is hyping the longstanding theory that Epstein was connected to Mossad, because it dovetails with their growing hostility to Israel. Suppose, though, that the crucial secret is that Epstein was a brilliant financial criminal, adept at moving money for shady international operators, and that his sexual habits were tolerated because of those talents, not because he had sexual kompromat on his friends. I'm not saying this is the truth, just citing it as a scenario that's plausible and also somewhat orphaned because it doesn't boost an ideological cause. Want all of The Times? Subscribe.

Scientists Witnessed the Birth of a Monster—8.3 Billion Years After It Happened

Here's what you'll learn when you read this story: Observations from NASA's James Webb Space Telescope and other telescopes have shown what appears to be a supermassive black hole forming right between two merging galaxies. There have been multiple hypotheses surrounding supermassive black hole formation, but these observations support the hypothesis that suggests these behemoths are the result of immense clouds of shocked and compressed gas collapsing in on themselves. Future observations with Webb may finally confirm how supermassive black holes come into being. Supermassive black holes lurk in almost every large galaxy, including our own, but their origins are more elusive. Did they appear after the demise of gargantuan stars in the early universe? Do they form from smaller black holes that merge? Is it possible they emerge from monstrous clouds of star-forming gas that collapse in on themselves? That last hypothesis might be onto something. The pair of galaxies merging into what is now known as the Infinity Galaxy (so named because of its uncanny resemblance to the infinity symbol) is 8.3 billion light-years away, meaning we are seeing events unfold as they did that many billions of years ago. Between them is what astronomers now believe to be a supermassive black hole (SMBH) in its infancy. Whatever the object is, it is accreting tons upon tons of material, and supermassive black holes are known for their voracious appetites. Observations of this galaxy and the thing spawning in the middle might be the first hard evidence of a supermassive black hole being born. Each of the galaxies that collided to form the Infinity Galaxy have their own glowing nuclei containing supermassive black holes, but the one supposedly forming in between is unrelated to either of them—its source is apparently something else. The mystery convinced astronomers Pieter van Dokkum of Yale University and Gabriel Brammer of the University of Copenhagen, who discovered the nascent black hole while analyzing images from the COSMOS-Web survey of NASA's James Webb Space Telescope, that what they were seeing was no ordinary star. Van Dokkum and Brammer backed their findings up by poring over data from observations made by the W.M. Keck Observatory, the Chandra X-Ray Observatory, and more data from the archives of the National Radio Astronomy Observatory's Very Large Array. It was already strange that this black hole was not hiding in the nucleus of a galaxy, never mind that it was at the beginning of its life. Shrouded by clouds of gas between the two galaxies was most likely a supermassive black hole that probably formed from gas that had been shocked and compressed during the galactic merger, then collapsed in on itself. Witnessing one being born is unprecedented. 'The gas spans the entire width of the system and was likely shocked and compressed at the collision site,' they and their colleagues said in a study soon to be published in the Astrophysical Journal Letters. 'We suggest that the SMBH formed within this gas in the immediate aftermath of the collision, when it was dense and highly turbulent.' There are two main hypotheses for how supermassive black holes form. The 'light seeds' theory claims that supermassive black holes are the product of black holes that form after massive stars go supernova, collapsing in on themselves in violent explosions. These black holes then merge into larger black holes. The problem is that it would not only take an extremely long time for a supermassive black hole to form this way, this theory also cannot explain the existence of supermassive black holes, already observed by Webb, which were around when the universe was still young. The 'heavy seeds' hypothesis suggests that immense clouds of gas that collapse usually form stars, but sometimes, the gases collapse directly into supermassive black holes. This is the theory that seems to align with the more recent observations. About a few hundred million years after the universe dawned, clouds of gas in the middle of what would become galaxies collapsed. Hiding in those gaseous clouds were the seeds of supermassive black holes, whose powerful outflows and magnetic storms caused surrounding gas to collapse into multitudes of new stars. This explains the high populations of stars around galactic nuclei. 'If our proposed scenario is confirmed, the Infinity galaxy provides an empirical demonstration that direct-collapse formation of SMBHs can happen in the right circumstances—something that has so far only been seen in simulations and through indirect observations,' Brammer and van Dokkum said. More observations with Webb and other telescopes could finally reveal what a supermassive black hole's baby pictures look like.
