Meet Aetosaurus arcuatus, a small, pig-snouted, alligator-like reptile -- now known to be one of only four vertebrates from the red sandstone of the Late Triassic New Haven.
If you lived in Fair Haven Heights around 200 million years ago, you may have shared your yard with this creature. Nowadays, the closest we will come to it is by exploring the quarry where its fossilized remains were found.
Come first to the library for a short talk about the fossil. Then, follow us for a field walk with Copeland MacClintock in Quarry Park, near the new Jepson School (41°17.955' N, 72°52.967' W). Parking is on Russell Street near the mouth of the quarry.
Mr. MacClintock is Senior Museum Assistant In Invertebrate Paleontology emeritus at Yale’s Peabody Museum of Natural History. His rediscovery in 2008 of the fossil site after years of its being lost to science is a story that delights.
