Karen Chin is investigating the question: How and what did dinosaurs eat? What evidence did she use to help her answer her questions?

Coprolites or Fossil ''poop'' is one method scientist (Palenontologist) like Karen employed to to discern what scientist eats.

Tryannosaurus Rex,(T.Rex) was the actual dinosaur that Karen understudied. This creature''s Coprolites  dated   about 65 million years ago, during the period of of Late Cretaceous. The T.Rex was a mammoth creature.With Coprolites of weight 17'' long, height 6'' and breadth of 15''. Consequently, Karen and colleagues concluded that, since T.Rex was the only huge  carnivorous at the Late Cretaceous period, technically  the Coprolites definitely belong to it.

Additionally, the  fragments of bone found in the Coprolites was  proof by Kreen to  conclude that T.Rex  crushed and chew  his preys, and therefore must be a Carnivore. And the it fed on Triceratops because the bone fragments in the Coprolites was found in the skull of Triceratops.

Explanation:

so the story tells of someone named kaushik choudhuri, but he does not narrate the story, a girl named hema does. hema tells the story in a second person point of view because you (the reader) are supposed to be the boy named kaushik.
