This is really cool, but I just want to say that paleontologists didn’t think Apatosaurus had sprawling limbs in the 1870s—they did in the 1900s, or rather some of them did.

This is what Camarasaurus looked like in 1877. By the late 1870s, paleontologists had a pretty good idea of what sauropods looked like. Abundant fossils from the western US had revealed most of the anatomy of sauropods, and it was obvious that they had upright limbs.

Well, obvious to most people. In the early 1900s, the herpetologists Oliver P. Hay and Gustav Tornier argued that the field of paleontology had it all wrong and that sauropods had sprawling limbs like lizards. This led to a huge, international argument between the American paleontologists who had been studying the fossils for years and the German Tornier. Even the Kaiser got involved.

This also led to what is possibly the most sarcastic academic paper ever written, William J. Holland’s epic takedown of Hay and Tornier’s claims. “As a contribution to the literature of caricature the success achieved is remarkable,” Holland says of Tornier’s reconstruction, before explaining how the deep pelvis of sauropods would have forced a sprawling Diplodocus to live in deep trenches:

“This might perhaps account for its early extinction,” Holland concludes.

Please read that paper if you have the time, it is an experience.

How did the turtle get its shell?

Turtles are some of the most interesting animals on Earth. They are the most complex of animals with hard shells. But scientists have long puzzled about how they evolved.

Meet Pappochelys or “grandfather turtle.” This little lizard from Germany is actually a close relative of the slow but adorable shelled reptiles, the turtles and tortoises.
