bones Diego Illoros They are similar to those of other members of the Machaeroidinae family, explains Ashley Post, co-author of the study and a paleontologist at the San Diego Museum of Natural History. What is unusual, however, is the shape and size of the teeth, the spaces between them, and the shape of that part of the chin that protrudes downward to protect the animal’s canine teeth.
Specialized in meat consumption
According to Post Diego Illoros It was one of the first mammals to be reasonably successful as an extreme carnivore – eating more than 70 percent of meat, as do domestic cats, lions, and today’s polar bears. But despite his teeth Diego Illoros Excellent carnivores, it may also have been one of the reasons for the animals’ extinction: they made it difficult for them to eat other foods. “at Diego Illoros There are very few molars left except for the incisors, similar to what happens in live cats today,” explains study author Shaun Zack of the University of Arizona School of Medicine in Phoenix.
The fossil provides new clues about how members of Machaeroidae once evolved. this is how he lived Diego Illoros At the same time for representatives Abatilorus It is from the same sub-family that lives in the Wenta Basin in Utah. Zack explains that this indicates that the macrooids were more diverse than previously thought. “It has always been possible that it was a single animal species, evolving over time and passing from one species to another. This is the first time that we have had fairly conclusive evidence that there are at least two different Macaroids, and completely different ones at the same time.”
