Some of the giant reptiles that ruled the ocean food chain during the time of the dinosaurs may have been able to control their own body temperatures, a new study suggests in the June 11th issue of the journal Science. These reptiles probably had high metabolic rates, which helped them dive deep and swim fast over large distances to catch their prey.

Three large, extinct swimming reptiles, the ichthyosaurs, plesiosaurs and mosasaurs, were the top ocean predators during the Mesozoic era, about 251 to 65 million years ago.

Most reptiles today are cold-blooded, meaning their body temperature is determined by how warm or cold their surroundings are. But, some of the modern ocean's top predators, tuna and swordfish, are “homeothermic” (aka warm-blooded), or able to keep their body temperatures at a constant temperature despite changing environmental conditions.

The relation of dinosaurs to birds is obvious tho it took a while to establish the link....some even coexisted.



It was very cool when "dad" walked out of the rainforest when I had my camera at had.

As virtually every school-aged child knows, birds are descended from dinosaurs. But holy toledo, does this newly discovered oviratporid ever look like a modern cassowary — right from the dramatic crest atop its head through to its long neck and ostrich-like shape. The paleontologists who discovered the dino are now studying modern cassowaries to get a better sense of its potential behaviour.

This newly-described oviratporid is called Corythoraptor jacobsi, and its fossilized remains — a beautifully preserved and practically complete skeleton — were uncovered near a train station in Ganzhou, Jiangxi Province, in southern China. The discovery of this new species shows that oviraptoridae — a group of bird-like, herbivorous and omnivorous dinosaurs — were among the most prolific and varied group of dinosaurs to live in the arid Ganzhou region during the Late Cretaceous period some 100 to 66 million years ago. The details of this finding were published today in Scientific Reports.


You should lose the skydaddy blinkers and get some understanding of this wonderful planet we evolved on....and the marvelous creatures we share it with now, and existed in the past. :coffee:
