Grass eating dinosaurs!

They've just found fossil phytoliths (the little silica granules in grass leaves) in some dinosaur poo! It seems that grasses are much older than we thought. The article notes that pollen had been recorded from India, South America and Africa and was a similar age (65-70 my).

Its certainly interesting and may mean a reinterpretation of several enigmatic fossils (maybe even some dinosaurs), and some early mammals. The article notes that previously a group called the gondwanatherians were thought to be beaver analogues, gnawing on wood, but the new finds indicates the hypsodont (hih-crowned) dentition is an adaptation to grazing (as in modern horses, etc).

Several email newsgroups are getting quite excited about this! I'm not surprised.
