plesiosaur -> πλησιόσαυρος

Plesiosaurs (pronounced /ˈpliːziəˌsɔɹ/) (Greek: plēsios/πλησίος meaning 'near' or 'close to' and sauros/σαυρος meaning 'lizard') were carnivorous aquatic (mostly marine) reptiles. After their discovery, they were somewhat fancifully said to have resembled "a snake threaded through the shell of a turtle", although they had no shell. The common name 'plesiosaur' is applied both to the 'true' plesiosaurs (Suborder Plesiosauroidea) which includes both long-necked (elasmosaurs) and short-necked (polycotylid) forms and to the larger taxonomic rank of Plesiosauria, which includes the pliosaurs. The pliosaurs were the short-necked, large-headed plesiosaurians that were the apex predators for much of the Mesozoic. There were many species of plesiosaurs, while most of them were not as large as Elasmosaurus.

Ενδείξεις ότι οι πλησιόσαυροι, ένα είδος δεινοσαύρων που ζούσαν στη θάλασσα, δεν γεννούσαν αυγά αλλά ένα μικρό που ίσως φρόντιζαν παρέχει απολιθωμένο εύρημα που βρέθηκε στις ΗΠΑ.

Όπως αναφέρουν Αμερικανοί γεωλόγοι σε άρθρο τους στο Science, το απολίθωμα μίας Polycotylus latippinus, μήκους πέντε μέτρων και ηλικίας 78 εκατομμυρίων ετών, βρέθηκε στο Κάνσας αλλά για περισσότερα από 20 χρόνια ήταν στο μουσείο περιμένοντας τους συντηρητές να αφαιρέσουν την πέτρα.

Eggless (amazing...) Ancient Sea Reptile

The remains of a giant sea creature are providing the first proof that these prehistoric reptiles gave birth to their young rather than laying eggs. Plesiosaurs, which lived at the time of dinosaurs, were large carnivorous sea animals with broad bodies and two pairs of flippers. Researchers have long questioned whether they would have been able to crawl onto land and lay eggs like other reptiles or gave birth in the water like whales.

"This is the first evidence of live birth in plesiosaurs -- an exciting find," said geology professor Judy A. Massare of the State University of New York, Brockport, who was not part of the research team.

The newly unveiled fossil was originally discovered in 1987 in Logan County in Kansas. Encased in rock, it had been stored in the basement of the National History Museum of Los Angeles County until resources were available to separate the bones for display at the museum.
