“…at a news conference at the Prince George’s County park Wednesday, officials and paleontologists announced the April discovery of the largest theropod fossil in eastern North America, a three-foot-long shin bone they hypothesize is from Acrocanthosaurus, a spiny, sharp-toothed carnivore from the Early Cretaceous period — about 38 feet long.

The discovery of additional dinosaur fossils soon followed, a trove of prehistory wrested from ironstone and clay. More than 100 fossils, estimated to be 115 million years old, have been found so far in a dinosaur bone bed along what had once been a river. A bone bed is the term paleontologists use to describe a concentration of bones of one or more species within a geologic layer.  The finding ‘marks a fundamental, extraordinary milestone in the field of paleontology and opens a window into our ancient world and to the species that once roamed this land,’ Peter A. Shapiro, chairman of the Maryland-National Capital Park and Planning Commission, said at a news conference.”

Astrodon johnstoni

by José Carlos Cortés on @ryuukibart

Name: Astrodon johnstoni

Name Meaning: Star Tooth

First Described: 1865

Described By: Leidy

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha, Plateosauria, Massopoda, Sauropodiformes, Anchisauria, Sauropoda, Gravisauria, Eusauropoda, Neosauropoda, Macronaria, Titanosauriformes

Astrodon is a titanosauriform that was originally named based on some teeth that were found, so yup, this is a tooth taxon! My favorite! It is now a nomen dubium, as none of the remains are considered sufficient enough to confirm its classification or distinctness. It lived in the Arundel Formation in Maryland, and this dates to the Albian age of the Early Cretaceous, around 112 million years ago. It lived alongside other dinosaurs such as Priconodon and Propanoplosaurus. There may also have been other dinosaurs such as a basal ceratopsian, Tenontosaurus, Dryptosaurus, Capitalsaurus, Coelurus, and Acrocanthosaurus. It may have also lived in Oklahoma, though its dubious remains make that questionable.
