Paleo Profile: Wucaiwan’s Ornamented Horned Face

The ceratopsians are among our favorite dinosaurs. These great horned herbivores included Triceratops, Styracosaurus, and Pentaceratops in their ranks, as well as celebrated newcomers like Nasutoceratops. But these were only some of the largest and last of their kind. A new find, reported by paleontologist Genglu Han and colleagues, is a reminder that ceratopsians started […]…

Paleo Profile: Spain’s High-Spined Herbivore

Sail backs were all the rage back in the Mesozoic. Some spinosaurs had them, with Spinosaurus itself bearing one of the most ornate of all, as well as the herbivorous Ouranosaurus, the shark-finned Concavenator, and the strange Deinocheirus, among others. And now, thanks to paleontologist José Miguel Gasulla and colleagues, another high-spined dinosaur has joined […]…

AUV Shows What Great White Sharks Do All Day

No creature has a reputation more fearsome than the great white shark. Despite all we’ve learned about them, including how they really don’t have much interest at in all eating us, movies and basic cable documentaries still show them as “machines” that do little more than “swim and eat and make little sharks.” And that’s […]…

A Crushing Bite Gives Sea Otters Their Cute Mugs

All otters are adorable. That’s as much of a fact as the existence of gravity. But among the 13 or so living otter species, none generate as many “Aww”s as Enhydra lutris, the sea otter. These fuzzballs are so cute, in fact, that we often overlook their bad behavior. But what is it that sets […]…

The Time 19th Century Paleontologists Punched it Out

Edward Drinker Cope wasn’t exactly the most even-keeled of paleontologists. The great “Bone Wars” that sparked a race to uncover America’s prehistory required the enmity of two fossil fanatics, after all, and Cope certainly proved himself capable of throwing jabs and haymakers in print at his friend-turned-nemesis Othniel Charles Marsh. Even among friends Cope was […]…

Paleo Profile: Amidala’s Strange Horn

Fossil mammals don’t get the attention they deserve. If you’ve ever been to the sprawling fossil halls of one of the great eastern museums – the American Museum of Natural History, the Field, the Carnegie, the Peabody – you know what I mean. The skeletons of ancient camels, horses, cats, sloths, and their beastly kin […]…

Paleo Profile: The Vereda Hilarco Beast

Isolation is essential to evolution. Whether they’re reproductive, behavioral, or geographic, barriers are what create opportunities for species to split off into something new. And given the odd array of mammals that evolved in South America during the time of the continent’s time as an island between the end of the Cretaceous and its connection […]…

Talara, Peru’s Great Ice Age Tar Trap

Earlier this year, as I ran around the Royal Ontario Museum fossil halls trying to take in as much as I could in the short time I had before a talk, an Ice Age fossil stopped me in my tracks. It was a fossil horse jaw, but unlike any I had seen before. The fossil […]…
