The marine life of Ohio included crinoids, snails, cephalopods, brachiopods, and fishes. Trilobites were also present, but their fossils are rare. [4] By the Permian period the sea had left completely. Local bodies of water were then lakes and rivers rather than saltwater. [3] Southeastern Ohio was a swamp-covered coastal plain. [4]

Interpretations by Engeser (1996–1998) suggests that nautiloids, and indeed cephalopods in general, should be split into two main clades: Palcephalopoda (including all the nautiloids except Orthocerida and Ascocerida) and Neocephalopoda (the rest of the cephalopods). Palcephalopoda is meant to correspond to groups which are closer to living ...
Ohio skies are filled this time of year with hundreds of species of birds flying north for the summer.. The height of the spring migration — known as The Biggest Week in American Birding — is ...
The cephalopods have a long geological history, with the first nautiloids found in late Cambrian strata. [1]The class developed during the middle Cambrian, and underwent pulses of diversification during the Ordovician period [2] to become diverse and dominant in the Paleozoic and Mesozoic seas.
The majority of birds that migrate through Ohio each spring will do so in May. "Then in June, we see the stragglers," Emmert said. Cuckoos are one of the most common species that tend to fly ...
From comparison with living cephalopods, particularly the shelled nautilus, some inferences about the biology of Cameroceras can be made. The head of the animal would have been soft muscular tissue situated at the opening of the shell, with the mantle (sheath-like body wall) lying within the shell for protection. Tentacles would have grown from ...
