"This block of sandstone contains a mass-death assemblage of 25 fossil gars. This group is unusual because each individual is preserved fully articulated in a three-dimensional belly-up death pose, indicating rapid burial after death."

 

 

From Florida Museum, Smilodon (saber-tooth cat) fossils are found all around the Americas, and Smilodon fatalis is just one of the species found in Florida. This specimen was collected not far from here in the Ichetucknee River in 1957

Great stuff! First class!! Thanks for posting them all. I knew that Sven has his connections, but the other ones are obviously also good to know!

I love this! Thanks for sharing, it’s making my morning a lot more interesting! I never realized quite how theropod-like heliocoprion teeth were. 

[Heavy_D]

Now those are some interesting teeth. Had never seen a helicoprion tooth whorl either.
