Analysis of the abdominal contents of two dinosaur fossil specimens reveals new information about their hunting and eating behavior. The full report is published Aug. 29 in the open access journal PLOS ONE.
The authors, led by Phil Bell of the Pipestone Creek Dinosaur Initiative in Canada, investigated the abdominal contents of two specimens of Sinocalliopteryx gigas, a small carnivorous dinosaur from China. One specimen appeared to have eaten a bird-like dinosaur, and the other's abdominal cavity contained the remains of at least two primitive birds. The researchers could not determine whether the prey had been actively hunted or scavenged, but other evidence suggests that the Sinocalliopteryx were adept stealth hunters who may have tackled prey more than a third their own size.
