quote:Originally posted by rahonavisHi Dr Beaver,This feels like nit-picking, but there were no grasslands in the late cretaceous. I think adult T. rex were probably too large to have inhabited forests. I imagine plains made up od whatever low lying plants passed for grass at the time were its likely stomping ground.
quote:A study of fossil dinosaur dung has for the first time confirmed that the ancient reptiles ate grass. Grass was previously thought to have become common only after the dinosaurs died out 65 million years ago. But grasses were probably not a very important part of dinosaur diets - the fossilised faeces show the big beasts ate many different types of plants
quote:The 65-67 million-year-old dung fossils, or coprolites, are thought to have been made by so-called titanosaur sauropods; large, vegetarian dinosaurs. "It's difficult to tell how widespread [grass grazing] was," Ms Strömberg told the BBC News website, "Dinosaurs seem to have been indiscriminate feeders." The study also sheds new light on the evolution of grass. Grasses are thought to have undergone a major diversification and geographic proliferation during the so-called Cenozoic, after the dinosaurs had gone extinct. But the researchers found at least five different types of grass in the droppings. This suggests grasses had already undergone substantial diversification in the Late Cretaceous, when the giant beasts still walked the Earth.

quote: Mickey,Mickey,Mickey,how can you say that about hyenas,they kill more fit animals than lyons,its just that they are weedy little things compared to lyons so they just walk up and take over the kill,the fact that this happens mainly at night,may make it less than common knowledge.
