This is another example of how the evolutionary timeline has had to shift. Grass has been thought to have evolved around 55 million years ago, but grass found in fossil dino poop shows that it must have been around at least 10 million years sooner. This is also another example of modern plants and animals living alongside of dinosaurs. Same fossils as are living today – no evidence of evolution!
