Recent studies have shown that some of the plant-eating dinosaurs were picky eaters; regardless of height, they selected their food according to texture and nutrition. For many years, it was thought that the herbivorous dinosaurs ate according to the height at which they could reach their food. The chemical data, however, has shown that the 150 million-year-old teeth had nutritional preferences and exhibited a more complicated behavior than previously believed. The long-held beliefs and conclusions have already been called into question by this revelation.
How Dinosaurs Select Their Food
The Texas Science & Natural History Museum's paleontologist Liam Norris and his team found that the herbivorous dinosaurs ate a variety of foods, from soft leaves to harder twigs. Variations that showed the food choices were indicated by their examination of the calcium isotopes. Similarly, the researchers found trends in dietary choices. For example, whereas Camarasaurus were thought to consume leaves from trees, they really consumed woody vegetation. Importantly, these dinosaurs' diets showed clear trends and how they adjusted to their surroundings in order to survive.
Using Calcium Clues to Decode the Dino Diets
Eutretauranosuchus most likely ate fish, according to a new examination of the isotope levels in the dinosaur's teeth. Allosaurus, on the other hand, avoided eating bones but enjoyed the flesh of other dinosaurs. Paul Barrett, a dinosaur specialist from the Natural History Museum, London, has complimented Norris and his colleagues for completing this investigation and has lauded this use of isotopes as a unique technique to dispute the previous results. The procedure is difficult, nevertheless, as paleontologist Michael Benton described it as a unique strategy to prove the new analysis. Additionally, he affirmed that the chemical indicators of nutrition can persist for millions of years.
