Top 10 things you may not know about dinosaurs, how much do you know? 3
In the previous article, we learned about the first 5 interesting things surrounding dinosaurs.
6. Why do some dinosaurs walk on 2 legs, while other species walk on 4 legs?
One of the common characteristics of dinosaurs is that the front legs are always shorter than the back legs.
The answer here is the `weight` factor.
7. How did dinosaurs take care of their eggs?
According to fossils that scientists have found, dinosaurs laid eggs and placed them in circles regularly and carefully in a nest dug deep in the soil.
8. Were the predecessors of dinosaurs very small creatures compared to them?
According to research, the ancestors of the dinosaurs – the species Lagosuchus, belonging to the primitive reptile group Archosaur, were only about the size of a rabbit: 50cm long, weighing 100 grams, with front legs shorter than the back legs like later dinosaurs.
The most famous ancient dinosaur is believed to be Eoraptor (meaning `dawn robber`), which lived in the Triassic period about 225 million years ago, discovered in 1991 in Argentina.
Later, scientists also found many other skeletons that were even smaller in size.
9. Some dinosaurs had the ability to regulate body temperature?
Normally, that should have been impossible because dinosaurs were reptiles.
Besides, according to research results from bone cross-sections of some small carnivorous dinosaurs, scientists have realized that if there are cold-blooded dinosaurs, there are also other species that must have cold blood.
10. When they grow up they are big, but when they first hatch they are tiny
Even for dinosaurs that are among the largest in size when mature, there are also tiny ones, completely different from human imagination.
Of course, in that case, the dinosaur egg couldn’t have been bigger.
Opposite.
