Predatory dinosaurs lived from about 235 to 65 million years ago

lovethee History

As interesting as it is to imagine dinosaurs being alive inmodern times, it is just as interesting that, in a sense, predatory dinosaurs really are still with us-and in a form we find bothfamiliar and often pleasing-for birds are direct descendants of predatory dinosaurs. And much as predatory dinosaurs were the chief land animals of their time, predaceous birds are the main killers of mammals and reptiles in many places. dinosaur manufacturer


“Lions and tigers and bears” and the fantasy animals of Oz and science fiction are fun, but, as a paleontologist, I prefer the stranger than fiction animals of the past. Paleontology, the study of fossil organisms, is, to me, a form of time travel. Dinosaur bones and the sediments they are preserved in are relics of past events • One of the fine things about paleo is that all you need is transportation, tents, a few tools, one person who can cook, the proper paleontological training, and there you are traveling back in time 145 million years. realistic dinosaur costume


Predatory dinosaurs lived from about 235 to 65 million years ago-give or take a million here and there-during the Mesozoic Era. The Mesozoic is split into the three periods. About halfway through the first period of the Era-the Triassic, which lasted from 248 to 213 million years before the present (MYBP) the first dinosaurs showed up, and they had to get along with a number of nondinosaurian predators* By the second period, the Jurassic (213-144 MYBP), predatory dinosaurs had become the sole big killers. The same was true through the third, the Cretaceous Period (144-65 MYBP), which also saw the first flourishing of birds. Dinosaurs were extin¬guished at the end of the Mesozoic Era, and the following era- the Cenozoic-was the age of mammals. Compared to the brief¬ness of our civilization, the span of predatory dinosaur existence appears vast. But dinosaurs are recent and short-lived compared to the Earth itself, which is celebrating its 4.5 billionth or so birthday.
