Now that spring has arrived, I thought I'd share a leaf that might seem a little too familiar!  Well it should—it's from a genus that is found all over North America today. Its closest living species is still found in the Southeast. Can you tell me the modern species, as well as this ancient one that dates back to Miocene? Their names are almost the same!

First person to correctly identify the fossil wins bragging rights for the week!

This week on Fossil Friday, I give you an incredibly easily identified fossil. I mean, come on, it's the whole body!  Plus, I'm going to tell you it's a synapsid from the Permian. What could be easier?

This week on Fossil Friday, I bring you one of the most famous fossils of all time. The jaw should look a little familiar to those who love fossils. But it's not the jaw that made this animal so interesting to paleontologists.

What was this animal? Where was it found? And why is it so important to our understanding of life on Earth?

Last week on Fossil Friday, my expectations were high. I gave you a single tooth and expected you to determine the entire animal once attached to it!

And you were all champs. Every commenter (except for Mr. Sloth man), got it right, correctly identifying the tooth as belonging to a mosasaur, a group of large extinct marine reptiles.

This week on Fossil Friday, I bring you a fossil that you can really sink your teeth into! Or maybe this animal would have sunk its teeth into you!

This air-breathing marine reptile dates back to the Jurassic and was found in what is now the Sahara Desert. Although they are considered to be a distant relative of the Komodo Dragon, researchers now think they are even more closely related to snakes.

This week on the Fossil Friday, I take you outside of the museum...many thousands of miles away, to an actual site in the desert. Josh Rosenau here at NCSE snapped this photo when he was traveling...where? I can't tell you! What is it? That is for you to figure out!

For those who are in love with fossils, this should be an easy one, as it comes from a UNSECO World Heritage Site. Others? Perhaps a Google search can get you started.
