For the exploration of dinosaurs, all humans have been working hard, and how
do humans determine the skin of dinosaurs? In fact, in the excavation of
dinosaur fossils, some fossils had dinosaur skin on them. The question of
whether Tyrannosaurus Rex has feathers has attracted the attention of many
dinosaur lovers. And there are many exaggerated recovery maps on the Internet.
The tyrannosaurus skin imprint fossils currently found are scales or chicken
skin-like traces, no feather imprints have been directly found, and no long
feather traces have appeared on the bones. Our Dinosaur Fossil Factory also
currently has fossil reproduction services. There is no evidence that
Tyrannosaurus rex has no long feathers. At least it is relatively certain that
it has feathers and it is certainly not full body coverage. Do the relatives of
Tyrannosaurus have clues? The answer is that no traces of feathers have been
found in the fossil tyrannosaurids currently excavated. Although no traces of
feathers have been found in Tyrannosaurids, there are indeed feathered members
in the entire evolutionary tree of Tyrannosaurids. Among them, there are feather
fossils of Emperor Dragon and Feather Dragon. Today we can only admire Amusement
Park Animatronic Dinosaur.
There is also a very important point, which is often forgotten when the
artists' brains are wide open. Animals with a larger body shape will have a
relatively reduced hair coverage, because their huge body shape can generate a
lot of heat, and excessive body hair is not conducive to heat dissipation
(except in extreme environments, such as mammoths). Through research, the
environment in which Tyrannosaurus Rex is located is not an extremely cold
climate. As an animal with an average body size of 7 and a half tons, if it is
covered with thick hair, it will be very detrimental to its survival.
Previously, feathered dinosaurs were considered petite and small, until the
discovery of the Feather King Dragon in 2012. The restoration pictures of the
"weed finch" who painted Tyrannosaurus Rex as a thick feather are basically just
entertainment. To sum up, it can be seen from the fossils with scaly traces that
the Tyrannosaurus Rex is not covered with feathers all over the body.
Considering the basic heat dissipation problem, it will not be a thick feather
like the "marijuana bird". However, from the "goose-like skin fossils" and the
prevalence of feathers in the osteosaurids, it can be guessed that Tyrannosaurus
may have feathers or a shallow layer of feathers on its body. But it could also
be bare scaleless skin + scales, like in Jurassic Park. However, verifying these
points needs to be proved by more relevant fossils.
The discovery of feather fossils by dinosaurs is nothing new. The first
dinosaur fossil with feather marks was discovered in 1996 in western Liaoning,
China. Since then, 1-2 feathered dinosaurs have been found almost every year.
These dinosaurs are basically from western Liaoning, China, because the
geological environment here is special and can retain feather traces. It has
also attracted the attention of scholars around the world for decades.
