MGS Portal to Recent News Stories on Fossils and Minerals

An ichthyosaur skeleton, probably collected by Mary Anning in the early 1800s and housed at the Royal College of Surgeons, London, was destroyed during Nazi bombing of the city in 1941. A loss to paleontology? Yes, but eight decades after the destruction, casts of the skeleton have been recently discovered, partly restoring to science the lost fossil, the first complete ichthyosaur skeleton ever found. A recent article in the New York Times tells the amazing story of these rediscovered casts. Links to this article and many other articles, reports, and blog postings highlighting recent fossil and mineral news can be found on the MGS WebSightings page. Please check it out.

Snaggletooth Shark Teeth From The Maryland Miocene

Pictured below is a selection of teeth from Hemipristis serra (snaggletooth shark) found at Bayfront Park at the northern end of the Calvert Cliffs. This site is 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.
