The End of the Cretaceous World and its Remains
Dinosaur dung fossils by M. Yamamoto
It has been said that herbivore dinosaur dung fossils are rarer than those of carnivores to find. But it seems I found lots of herbivore dung fossils. Firstly, photos of herbivore dung fossils are shown below. They are like balls of fiver. So I decided they are herbivorous dinosaur dung fossils. I always try to decide what they are by observing their shapes and appearances. I am a medical doctor and an instant fossil hunter. I cannot analyze for calcium phosphate.
Secondly, photos of carnivorous dinosaur fossils are shown.
These dungs came from dinosaurs which had flesh
These dungs came from dinosaurs which had flesh and bones
These dungs are from dinosaurs which had flesh and gut. Note small amount of fiber on their surfaces.

The dung above was sitting on this side
during fossilization process proceeded.
This dung was evacuated from high place
and a dent was made on landing.
These dungs were in the intestine at the time of their death. The intestine was fossilized before they went rotten. There is a possibility we are able to sequence dino-DNA because gut muscles seem well preserved. Photos are shown below.
