What a fun day DIL Corinne and her two youngest girls had yesterday.
They went with a local scientist to expert to look for fossils on the river sandbars at low tide.
This area was once the home to the huge dinosaur-era Megladon shark. Megladons raised their pups in this area, which was once all under water.

They did find a shark tooth–a very big one. Turns out it was from an Augustiden shark, the great grandfather to the Megladon shark. The very big tooth looks just like the one pictured here.

Pictures show they came home dirty and happy.
