They read a description of their findings before the American Philosophical Society inbut the report of their discovery would not be published for 75 years. The Connecticut Valley of the northeastern United States was the scene of the first Anchisaurus discovery.

Anchisaurus is a genus of basal sauropodomorph dinosaur. Anchisaurus was coined as a replacement name for " Amphisaurus ", which was itself a replacement name for Hitchcock's " Megadactylus ", both of which had already been used for other animals. Sauropodomorph remains were first documented in North America in , when some bones nearly 1. Solomon Ellsworth Jr. At the time of their discovery it was thought that the bones might be those of a human, [3] but the presence of tail vertebrae falsified that idea. They are now recognized as those of an indeterminate sauropodomorph, possibly more closely related to the plateosaurian prosauropods.

Early 19th-century newspapers and periodicals are filled with numerous accounts of the discovery of the fossilized bones of extinct mega-fauna, such as those of the mastodons and mammoths that once roamed the prairies and forests of prehistoric America. Dinosaurs in the United States are usually associated with the western states such as Utah, Montana, and Wyoming, where large fossilized deposits have been excavated. It may be surprising that one of the most significant discoveries in paleontology happened on the east coast in New Jersey. In , a number of large bones were uncovered on the property of Mr. Hopkins put the remains on display at his farm, which attracted friends and curiosity seekers. In the summer of , they caught the attention of William Parker Foulke, a fossil collector. Believing there were perhaps other remains waiting to be found, Foulke began to dig at the site. He was rewarded for his efforts and curiosity when he and his workmen discovered the bones of a large unknown creature buried nine feet below the surface. Foulke had discovered the first almost complete dinosaur skeleton ever found in the United States. The discovery would change the field of paleontology. The fossils were sent to the Academy of Natural Sciences in Philadelphia, where by it would become the first dinosaur skeleton to be mounted for public display under the direction of Dr. Joseph Leidy pictured above. Leidy, a famed anatomist, aided in its reconstruction and drew artistic sketches of the dinosaur. Known as a duck-billed dinosaur, other creatures of the same species have been discovered in New Jersey and elsewhere.

Paleontology in Connecticut refers to paleontological research occurring within or conducted by people from the U. Apart from its famous dinosaur tracks, the fossil record in Connecticut is relatively sparse. At the time, Pangaea was beginning to divide and local rift valleys became massive lakes. A wide variety of vegetation, invertebrates and reptiles are known from Triassic Connecticut. During the Early Jurassic local dinosaurs left behind an abundance of footprints that would later fossilize. The first scientifically verified dinosaur bones discovered in North America were uncovered during the excavation of a well in Connecticut. Other notable finds include the aetosaur Stegomus , the phytosaur Clepsysaurus , and the prosauropod dinosaur Anchisaurus.

Who gets credit for the first dinosaur in North America depends on one's definition of a description and a fossil. DOI: In the year paleontologists will celebrate the th anniversary of the first description of a dinosaur fossil from North America. In March Joseph Leidy of Philadelphia wrote a brief paper describing and naming four kinds of million-year-old reptilian teeth that had been discovered the previous year in the Cretaceous beds of the Judith River region of Montana. Without any of the media hoopla that accompanies many dinosaur discoveries today, he showed that two of the new reptiles were unquestionably dinosaurs, as judged from comparison with discoveries made in England 30 years before. These were the first American dinosaurs.
