The man-eaters of Tsavo, two lions that killed railroad workers in Kenya more than a century ago, have inspired legends, movies and a lot of research papers trying to explain what drove the big cats to prey on humans (a rare menu choice for Panthera leo). A study out today finds that, in one crucial way, the infamous killers were a lot like — surprise — zoo animals. Read More
Be glad our species wasn’t around some 400 million years ago…we would have had to contend with giant sea scorpions, some more than 10 feet in length and capable of prowling about on land in search of a meal. And that’s not all: Researchers reveal that at least one of these Monsters of Deep Time had a particularly violent — and unusual — way of dispatching its prey.
Well, well, well… looks like it’s time for yet another shake-up in the dinosaur story, this time courtesy of one of the animals’ early relatives, Teleocrater rhadinus. The first description of the animal, published today, reveals the conventional chronology of how dinosaurs bodies evolved might be just a wee bit off, give or take several million years. Read More
Who doesn’t love free stuff? I know I do. And a renovation of open access evolution database TimeTree is a treasure chest of data for the taking. Read More
It’s the mass extinction you probably haven’t heard about, because for a long time researchers have questioned whether it even existed. But a growing body of evidence, including a study published today, has strengthened the case for Olson’s Extinction — which played a role in our species eventually dominating the planet, for better or worse (mostly worse).
For one unfortunate medieval Italian, the cradle was the grave. It’s commonly called coffin birth, though researchers use the terms post-mortem fetal extrusion or expulsion. And yes, it is what you think it is — but the latest case documented by scientists, from 14th century Liguria, reveals there was more to the story. Read More
The eyes may be the window to the soul, but for paleontologists, reconstructing a dinosaur face opens doors into how it may have perceived and interacted with its environment — as well as some features it shared with distant evolutionary kin.
Researchers report being able to put a face to the name of 75-million-year-old Daspletosaurus horneri, a newly described member of one of Dinosauria’s most famous lineages, and discover the animal was the touchy-feely sort.
Ask any obsessive dino-phile above kindergarten age to explain the dinosaur family tree and it’s likely the first thing you’ll hear is that all dinosaur species fall into one of two groups. It’s a core concept upon which our entire understanding of dinosaurs is built. But according to a new study, we got that most fundamental aspect of dinosaur evolution completely wrong. Oops.

Researchers who want to study the nature of Earth’s original crust find themselves between a rock and a hard place: Our planet’s top layer is constantly wearing down in one spot and building up in another, continents colliding or slip-sliding past each other in the great mosh pit of plate tectonics. You might have figured none of the early crust was even still around. New research shows you would have figured wrong. Read More
If, like me, you like fossils and you like sharks, you’re in luck. A recent re-look at a fossil found more than a decade ago has answered a big question about the story of sharks’ evolution.
