Why do we find fossil shark teeth in such a variety of colors?
Both of these fossil teeth came from the same species of extinct shark--Otodus obliquus--but why are they different colors? Our paleontologist Richard Hulbert has an explanation! It helps to know they came from two different Florida fossil sites...
Some fossil dig sites are actually IN a river, like this one in Florida
Imagine spending #FossilFriday in a river. Our collection holds >11,000 vertebrate fossils from the Ichetucknee, a 4.1 mile long river not far from our Museum. Specimens include American lion (Panthera atrox, shown), osprey (Pandion haliaetus), alligator gar (Atractosteus spatula) & Otodus obliquus, an extinct shark. #fossils #extinctshark #fossilshark #sharkteeth #FloridaFossils
Jaguars once roamed as far as Florida! These fossils are common.
Jaguars (Panthera onca) first dispersed to North America across the Bering Land Bridge in the Pleistocene and were much larger than those living today in Central and South America. Although they don't live in Florida anymore, they were once common. #fossils #jaguars #BigCats #FloridaFossils
Iconic Skeletons: Giant Ground Sloth
Armed with huge claws, this Giant Ground Sloth specimen stands at 15 feet tall, and is estimated to have weighed more than 3 tons. It's the largest sloth species to migrate north during the Great American Interchange roughly 3 million years ago. The #fossil in our exhibit hall is a popular specimen! #FloridaFossils
Iconic Skeletons: Mammoths vs. Mastodons
Columbian mammoth vs. American mastodon! The first thing you see when you walk into our galleries is a 14-foot-tall, 16,000-year-old Columbian #mammoth skeleton. Around the corner is an American #mastodon. Both of these #fossils were discovered in nearby Aucilla River. Discover the differences between these two ancient proboscideans that once walked the earth thousands of years ago. #FloridaFossils
