Description
Reconstruction of megaraptoran Siats meekerorum from the Cenomanian of Cedar Mountain Formation (Utah). This very large theropod (estimated length of occurrence that has not reached maturity is estimated at 11.9, and the mass is 4 tons) was the last carnosaur from North America. Then it was replaced by tyrannosaurs.The second attempt in a new style. Protofeather-quill-scaled covers, as and proportions are speculative, since the only specimen was fragmented, with cranial material is unknown.

I must say that the theory that this animal was responsible for keeping T.rex small is a lie. Because the tyrannosaurus were already in the process of ascending their evolution when all the North American carcharodontosaurs were extinct or it was not a fast process, something was killing the American carcharodontosaurs, there is an extreme possibility that the ancestors of the t.rex were related to this mass extinction of carcharodontosaurs that was during the Cretaceous, before T. Rex appeared.

You made this look like a dinosaur that has little problem spending energy. That's what I like about slimmer dinosaurs. They're not as bulky and therefore likely could run faster.

Yep, unfortunately.

Because really, very few reconstructions of this animal, although it plays an important role in understanding the faunal composition of the Cretaceous of North America.

your saying that reconstruction is still inaccurate?

I didn't say that. This reconstruction is very speculative, it has an equal chance to be both right and wrong.

Во! Тут конечности прорисованы детально, фигурно. И вообще рисунок качественный. Единственное смущает - бедро вроде бы немного усохшее для такой туши.

Спасибо! Бедро кажется усохшим
из-за ракурса.
