Hi guys,

The conference is over and it was a blast. I saw a lot of good talks and there is some great research going on. I also looked at the fossils on display in the University of Bristol Geology Department. I took pictures and posted them below (some of them are on their sides and I haven't been able to fix that).

This is a horseshoe crab from rocks in the Upper Jurassic Period, about 162 to 151 million years ago. Horseshoe crabs first appeared in the Devonian Period, 400 million years ago. Species of horseshoe crabs are around today and haven’t changed much, as we can see from this ancestor!

This is Eryops, an amphibian found in rock formations from the Lower Permian Period, about 295 million years old. Eryops is important because it is an example of an amphibian making the transition from a completely aquatic lifestyle to spending time on land.

This is one of my favorite early amphibians, Diplocaulus. It lived in North America during the Permian period from 299 to 251 million years ago. The weird skull may have helped it swim or defend itself from predators.

Does this look familiar? This is the front left leg of a sauropod (the long-neck dinosaurs) called Camarasaurus. It lived from in North America from 155 to 145 million years ago in the late Jurassic Period. They grew to about 60 feet in length! We have our own sauropod (Apatosaurus) on display at the UW Geological Museum.

Here’s another creature that we have on display at the UW Geological Museum. This is Ichthyosaurus, a marine reptile that lived during the early Jurassic period, from 199 to 189 million years ago. It lived in the ocean that covered Europe at that time. The casted specimen on display at our museum has two skeletons: a mother that is giving birth to its baby!

How would you like to run into this big cat? This is Smilodon, also known as the saber-toothed cat (like Diego from “Ice Age”). Smilodon lived in North and South America during the Pleistocene and Holocene epochs, from 1.8 million years ago to 10,000 years ago.

That’s it for today. I’ll have more pictures to post in the next few days!
