From Live Science:
ShareFossil collectors have discovered a prehistoric graveyard buried in Florida’s Steinhatchee River. The site has yielded a remarkable collection of more than 500 fossils dating back roughly half a million years. It was full of exceptionally well-preserved bones from ancient mammals, including horses, giant armadillos, sloths and possibly a new species of tapir.
These fossils remained hidden until 2022, when fossil collectors Robert Sinibaldi and Joseph Branin stumbled upon them during a routine diving expedition in the river’s murky waters. After Branin spotted horse teeth sticking out of the sediment, the pair uncovered a hoof core and a tapir skull, signaling a potential major discovery.
“It wasn’t just quantity, it was quality,” Sinibaldi said in a statement released on Feb. 12 by the Florida Museum of Natural History. “We knew we had an important site, but we didn’t know how important.”
The Florida Museum recognized the significance of the find and dated it to the middle of the Irvingtonian North American Land Mammal Age (1.6 million–250,000 years ago)—an evolutionary transition period with a sparse fossil record. (Read more.)
