Fossil Ray Tooth Plate Myliobatis sp Aquia Formation Palaeocene Maryland USA Genuine

Fossil Ray – Myliobatis sp. (Eagle Ray Tooth Plate)

Geological Period: Late Palaeocene (Thanetian Stage)

Age: Approximately 59 to 56 million years ago

Formation: Aquia Formation

Locality: Wades Bay, Charles County, Maryland, USA

This listing features a genuine tooth plate from Myliobatis sp., a genus of eagle ray that once inhabited the warm, shallow seas of what is now the Atlantic Coastal Plain of North America. This fossil comes from the Aquia Formation, a well-known Late Palaeocene marine deposit exposed along the Potomac River and its tributaries.

The Myliobatis tooth plate is characterised by its flat, pavement-like structure, composed of interlocking teeth adapted for crushing hard-shelled prey such as mollusks and crustaceans. These rays were part of the elasmobranch lineage, related to modern rays and sharks, and played an important ecological role in Palaeocene marine ecosystems.

The Aquia Formation, dating to the Thanetian stage of the Palaeocene, consists of glauconitic sands and silts deposited in a shallow marine environment. Fossils from this formation include a rich variety of shark teeth, ray dentition, bony fish, and marine reptiles.

Striatolamia macrota Shark Tooth Fossil - Paleocene, USA | Genuine + COA

Authentic Striatolamia macrota Fossil Shark Tooth – Late Paleocene, Aquia Formation

This is a genuine Striatolamia macrota fossil shark tooth, carefully sourced from the Late Paleocene (Thanetian) deposits of the Aquia Formation, Piscataway Member, at Wades Bay, Charles County, Maryland, USA. Dating back approximately 59–56 million years, this well-preserved tooth comes from an extinct species of sand tiger shark that thrived in prehistoric marine environments.

Striatolamia macrota belonged to the family Odontaspididae and was an early relative of modern sand tiger sharks. Known for their elongated, narrow teeth with sharp cusps, these sharks were likely opportunistic predators that fed on fish and other marine life.

Geology & Formation:

The Aquia Formation is a significant Paleocene-aged marine deposit found in the mid-Atlantic United States. The Piscataway Member is particularly rich in well-preserved vertebrate fossils, including numerous species of sharks, rays, and bony fish. This formation provides valuable insight into marine ecosystems following the mass extinction that ended the Cretaceous period.
