There are many theories about why dinosaurs became extinct. Instead, dinosaurs, like many extinct forms of reptile sub-groups, did not exhibit characteristics which were traditionally regarded as reptilian, such as a sprawling limb posture or ectothermy (colloquially referred to as "cold-bloodedness").

On the other hand, because lower quality food is much more abundant than higher quality food, large herbivores cannot afford to search for the more dispersed high-quality food items due to their very high absolute food intake requirement ( Demment & Van Soest, 1985 ). With body mass increase driven by the selective advantages of large body size, animal lineages will increase in body size until they reach the limit determined by the interplay of bauplan, biology, and resource availability.

Thomas Holtz, a geologist from the University of Maryland, and his colleagues suggest that these dental characteristics may have evolved to accommodate a diet that included eggs, worms, insects and plants. Those that had existed on the dry Triassic supercontinent were quite different from those that lived on the scattered landmasses of the Cretaceous. Simply put, this is what "Disney's Dinosaur" had mad delusions of being. Shouldn't animals still be the same size as they were during the time of the dinosaurs?

With more than 700 species, their remains exhibit an astonishing, often bizarre, variety of form and habit. But I think you're right, fish a reptiles have amazing strength, or say ants compared to their body weight. Kids want to know how the dinosaurs grew so large. The pollen from the stamen has to reach the pistil and make a pollen tube to the base of the flower, the ovary, and the ovules, where the egg cells are. Here also two tannim passages; Ezek 29:3: "Thus saith the Lord Yahweh: Behold, I am against thee, Pharaoh king of Egypt, the great monster (the King James Version "dragon") that lieth in the midst of his rivers, that hath said, My river is mine own, and I have made it for myself"; and Ezek 32:2: "Son of man, take up a lamentation over Pharaoh king of Egypt, and say unto him, Thou wast likened unto a young lion of the nations: yet art thou as a monster (the English Revised Version "dragon," the King James Version "whale") in the seas; and thou didst break forth with thy rivers and troubledst the waters with thy feet, and fouledst their rivers."

But the dino-to-bird advocates counter with equally powerful arguments against Feduccia’s ‘trees-down’ (arboreal) theory. So far, so good; the sauropods look ridiculous and should not be munching water weeds in a swamp, but that can be put down to a combination of 1960's paleontological ignorance and artistic license. Explorers and natives in Africa have reported sighting dinosaur-like creatures, even in the twentieth century. 46 These have usually been confined to out-of-the-way places such as lakes deep in the Congo jungles.

Placerias was a large, herding herbivore with a horny beak and a pair of downward-pointing tusks. Although dinosaurs' fossils have been known since 1818, the term dinosaur (deinos = terrifying; sauros = lizard) was coined by the English anatomist Sir Richard Owen in 1842.
