Plesioteuthis
''Plesioteuthis'' is an extinct genus of squids, belonging to the family Plesioteuthididae. This genus was first described in 1859, and its fossils were found in the well-known Solnhofen field in Germany. Species Species within this genus include: *''Plesioteuthis prisca'' (the type species) (Rueppel, 1829) † *''Plesioteuthis subovata'' (G.G. Münster, 1846 ) † The ''Plesioteuthis arcuata'' is not considered a member of this genus. Together with its close relatives (including '' Rhomboteuthis'', ''Dorateuthis'' and '' Boreopeltis'') this animal has often been considered an archaic relative of the octopus (Octopodiformes) due to the fact that more than eight tentacles have never been found in fossils. However, the structure of the beak of Plesioteuthis resembles that of the Decapodiformes. Fossil record These squids lived in the Tithonian, Upper Jurassic (Age range from 155.7 to 150.8 million years ago) and their fossils were found in Germany.Sepkoski, JacSepkoski's Onli ...

Rhamphorhynchus Eating Plesioteuthis
''Rhamphorhynchus'' (, from Ancient Greek ''rhamphos'' meaning "beak" and ''rhynchus'' meaning "snout") is a genus of long-tailed pterosaurs in the Jurassic period. Less specialized than contemporary, short-tailed pterodactyloid pterosaurs such as ''Pterodactylus'', it had a long tail, stiffened with ligaments, which ended in a characteristic soft-tissue tail vane. The mouth of ''Rhamphorhynchus'' housed needle-like teeth, which were angled forward, with a curved, sharp, beak-like tip lacking teeth, indicating a diet mainly of fish; indeed, fish and cephalopod remains are frequently found in ''Rhamphorhynchus'' abdominal contents, as well as in their coprolites. Although fragmentary fossil remains possibly belonging to ''Rhamphorhynchus'' have been found in England, Tanzania, and Spain, the best preserved specimens come from the Solnhofen limestone of Bavaria, Germany. Many of these fossils preserve not only the bones but impressions of soft tissues, such as wing membranes. Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
