Why “The Extinction of the Dinosaurs” is Misleading

It’s well-known that about 65 million years ago, something happened. An event so big that it caused a global mass extinction, dramatically changing ecosystems all over the world. This left such a clear mark in the geologic record that scientists knew about the extinction long before they found evidence of possible causes (in the form of an asteroid crater or huge amounts of volcanic rock).

The most famous effect of this event – and the reason most people have heard of it – was the disappearance of the dinosaurs. Scientists may call it the end-Cretaceous mass extinction (since it happened at the end of the Cretaceous Period), or the K-Pg mass extinction (“K” for Cretaceous and “Pg” for Paleogene, the Period that came next), but for most of the general public, it’s known as “the Extinction of the Dinosaurs.”

But this is a misleading name. Here’s why:

Psittacosaurus and the Colorful Dinosaur Revolution

Within the last decade, paleontologists have discovered how to unlock the color of extinct organisms, and I think it is one of the most exciting and thought-provoking modern advancements in the field. I’ve written about it no less than four times on this blog (one, two, three, four!), and now I feel obligated to write about it again.

It has been about a month now since the unveiling of the “most accurate depiction of a dinosaur ever,” and the fanfare was suitably loud. Now, I’d like to take a look over what we know about this dinosaur, and where it fits into this grand paleontological revolution we're living through.

Was Lightning a Problem for Tall Dinosaurs?

The other day I came across this question and was shocked that I hadn’t thought about it before.

Everyone knows lightning loves striking tall objects. Many dinosaurs stood 15-20 feet tall, and big sauropods holding their necks upright may have peered down on the world from 40 or 50 feet up! Were they just giant walking lightning rods?

What a great question! Let’s break it down.

What's New In Paleontology? Highlights from SVPCA 2016. (Part 2)

Last week, paleontologists gathered in Liverpool for the 64th Annual Symposium for Vertebrate Paleontology and Comparative Anatomy (SVPCA). I was unable to attend, mostly because of that big ocean sitting in the way (actually I’ve never been to SVPCA, I’d love to go) but I did get a hold of the abstract book. Lots of great talks and posters this year.

Here, I’ll go through some of my personal favorite highlights from this year’s meeting. I won’t have all the details, since I’m mostly going by the abstracts and not the full presentations, but I will be offering a glimpse into what’s currently happening in the field of paleontological research.
