Scientists thought this fossil was a teen T. rex. Turns out it's a new tyrannosaur A new look at the "Dueling Dinosaurs" fossil reveals that Tyrannosaurus rex was not the only tyrannosaur roaming the land.

Hurricane Melissa Literally Made the Earth Shake Hundreds of Miles Away Seismometers picked up the ferocious winds and waves of Hurricane Melissa, showing how the tools can be used to better understand storms today and those from the past

NEW: Hurricane Melissa was such a monstrous tempest that it was literally shaking the Earth as far away as Florida, where seismometers picked up its stormquakes.

Here’s how seismometers can also shine a light on hurricanes long gone.

Looks incredible. Unfortunately we cannot attend.

Damn! Now that’s raising the bar! Time to find an even spikier Desmatosuchus.

A photo of the fossilized remains of Prestosuchus on display in the Museum. The animal is quadrupel and low to the ground. It has a dinosaur-like skull.

Meet Prestosuchus chiniquensis. It lived in what’s now Brazil some 210 million years ago. Although it was a large animal with big claws & a huge head with sharp-toothed jaws, it wasn't a dinosaur—it's actually a close relative of crocodylomorphs.

Huenesuchus is an objective synonym of Prestosuchus while ‘class-group names’ do not exist in and are not regulated by the ICZN: a response to Kischlat A recent revision by Kischlat of the genus Prestosuchus (generally attributed to Huene) determined that it was an unavailable nomen nudum and proposed the new genus Huenesuchus to contain the species ...

In 2023, a erm.... controversial paper tried to rename Prestosuchus to Huenesuchus based on an egregious misapplication of the ICZN. My rebuttal of this is finally out, open access in @revbraspaleontol.bsky.social sbpbrasil.org/publications...

Most likely one of the Aetosaur specimens. Possibly Sierritasuchus?

The ornithopod Iguanodon was described on February 10, 1825. And on this day, is February 10, 2025.
It’s been exactly 200 years since the “iguana tooth” dinosaur was described and named in a scientific paper!

We certainly know the answer to that question…

What a great find for Triassic paleontology.
