Big Meals mean Big Guts
Triceratops ate and ate and ate, probably both day and night. Living on a diet of plants requires a sizable digestive tract, and the dinosaur's stomach and intestines probably filled much of its barrel-shaped abdomen.
Like cows today, Triceratops probably had countless bacteria and fungi in their guts that helped break down plant cellulose into glucose and other nutrients. |
