Do dinosaurs have spinal cord?
The first is that many dinosaurs had noticeable expansions of their spinal cords around their limbs–a feature that left its mark in the size of the neural canal in the vertebrae. This isn’t unusual.
How could dinosaurs get so big?
Dinosaurs lived during the Triassic, Jurassic and Cretaceous. During these periods, the climate was much warmer, with CO₂ levels over four times higher than today. This produced abundant plant life, and herbivorous dinosaurs may have evolved large bodies partly because there was enough food to support them.
How many vertebrae Did dinosaurs have?
Ancestrally, dinosaurs showed approximately 50 caudal vertebrae, although their number, size, and shape varied considerably in the separate groups. The number of caudals decreased along the evolutionary line leading to modern birds; in the latter, the remaining caudals are fused together into a pygostyle.
Did dinosaur had 2 brains?
No, completely false. The two-brain theory was a mere myth. The existence of an enlarged neural canal near the hip region of huge dinosaurs like Stegosaurus was initially thought of as the second brain’s location, to control the motions of the tail. Paleontologists have found no proof for this claim.
What dinosaur has 2 teeth?
Nigersaurus
Its skull was very specialised for feeding, with large fenestrae and thin bones. It had a wide muzzle filled with more than 500 teeth, which were replaced at a rapid rate: around every 14 days….Nigersaurus.

What dinosaur has the most horns?
The most horns on an animal ever is 15, as borne by the prehistoric ceratopsian (horned) dinosaur Kosmoceratops richardsoni, which lived approximately 76 million years ago during the Late Cretaceous in the southern region of what is now the state of Utah in the USA.
Do dinosaurs have shoulders?
Basal Ornithopods, early Theropods and dinosaurs close to evolutionary split into Aves (birds) were included in the research. The long axis of the scapular blade (shoulder bone) was found to be most horizontal in bipedal Saurischians, most vertical in basal members of the Ornithopoda, and intermediate in Hadrosauroids.
