How did vegetarian 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.

Can carnivorous animals survive without meat?

Some carnivores, called obligate carnivores, depend only on meat for survival. Their bodies cannot digest plants properly. Plants do not provide enough nutrients for obligate carnivores. All cats, from small house cats to huge tigers, are obligate carnivores.

Can a lion survive on a vegan diet?

Can lions be vegan? The obvious answer is, no, because they can’t thrive on plants. They’re obligate carnivores, meaning that eating a meat-based diet is literally in their biology.

What is the largest mammal to ever walk the earth?

What are the characteristics of a sauropods?

Many near-complete specimens lack heads, tail tips and limbs. Sauropods were herbivorous (plant-eating), usually quite long-necked [12] quadrupeds (four-legged), often with spatulate (spatula-shaped: broad at the tip, narrow at the neck) teeth. They had tiny heads, massive bodies, and most had long tails.

How long is the longest sauropod?

Supersaurus, at 33 to 34 metres (108 to 112 ft) long, [16] was the longest sauropod known from reasonably complete remains, but others, like the old record holder, Diplodocus, were also extremely long.

Why is the sauropod Brachytrachelopan the shortest?

The diplodocoid sauropod Brachytrachelopan was the shortest member of its group because of its unusually short neck. Unlike other sauropods, whose necks could grow to up to four times the length of their backs, the neck of Brachytrachelopan was shorter than its backbone.

When did Sauropods first appear?

Sauropods first appeared in the late Triassic Period, where they somewhat resembled the closely related (and possibly ancestral) group “Prosauropoda”. By the Late Jurassic (150 million years ago), sauropods had become widespread (especially the diplodocids and brachiosaurids).
