MGS Portal to News Stories on Fossils and Minerals

Sixteen years ago, a dog named Raffles on an outing with his owner on the shoreline at Lyme Regis, England, began scratching in the sand. He'd uncovered a vertebra which, as it turned out, was the first of 750 fossil bones found at the site of a plesiosaur from the lower Jurassic. Remarkably, these bones retained their three dimensional shape and were not flattened as is true of nearly all of those from the period. A recent article in The Guardian newspaper (link) describes the find and features a picture of the skeleton as well as one of Raffles.

Links to this and other paleontological and geological articles on the web can be found at the MGS WebSightings page.

Snaggletooth Shark Teeth From The Maryland Miocene

Pictured below is a selection of teeth from Hemipristis serra (snaggletooth shark) found at the northern end of the Calvert Cliffs south of Bayfront Park (also known as Brownie's Beach). These teeth are Miocene in age and were collected by MGS member Jim Stedman as "float" along the beach, the teeth having eroded out of the cliffs. The largest of these teeth is about 3 cm in length on the slant. At the present time, by resolution of the town of Chesapeake Beach, MD, only residents of the town are permitted to access Brownie's Beach.
