Researchers have discovered that some giant herbivore dinosaurs could not have adopted the strictly vegetarian weight loss plan most anticipated them to have. Some apparently additionally ate crustaceans like crabs, a minimum of on the facet. Researchers in Utah have been learning coprolites or fossilized dung and located stays of shelled animals in it. The outcomes of their research have been launched in an earlier September difficulty of the journal Scientific Stories.
Researchers Discovered Shelled Animals-Consuming Herbivore Dinosaurs
It’s troublesome to find concrete proof of what a big herbivore dinosaur ate. Often, paleontologists will discover a specimen with intact intestine contents, however coprolites are even rarer. Most such fossilized stays come from carnivorous dinosaurs since they’re famous to include minerals from the bones of their prey, minerals that additionally helped their preservation.
Karen Chin, a paleontologist from the College of Colorado Boulder, has been searching for coprolites from herbivorous dinosaurs for years. In 2007, she discovered coprolites containing rotten wooden in Montana. Again in 2013, she discovered comparable coprolites in southern Utah.
Together with fragments of wooden, they contained constructions that seemed like elements of a claw or the leg of a crustacean. The paleontologist consulted a colleague, Rodney Feldmann, who stated they seemed as if they’d come from a crab or crayfish.
The Utah fossils have been dated to be round 75 million years previous and had in all probability been produced by hadrosaurs. These had duck-like payments and might be about 20 ft lengthy. Chin notes that fashionable birds that often comply with a vegetarian weight loss plan will typically eat protein sources like bugs earlier than laying eggs.
A big herbivore dinosaur couldn’t get the wanted protein from bugs. Nevertheless, they might get these from consuming the bugs and fungi in a rotten log in addition to larger shelled animals, for instance, crabs.
Not all researchers consider that the hadrosaurs have been intentionally consuming crabs or the rotten wooden that contained them. Jordan Mallon, a paleontologist with Ottawa’s Canadian Museum of Nature, identified that hadrosaurs, given their dimension, would have been indiscriminate eaters. He believes it extra seemingly that the hadrosaurs in all probability ate the occasional crayfish by chance.
