Its skull raised a much bigger question<\/h2>\n
The newly named Infernogallus jamesi<\/em> was discovered in the Hell Creek Formation, home to many fossils of T. rex and Triceratops.<\/p>\n Although Infernogallus<\/em> lived alongside some of the largest dinosaurs<\/strong> ever identified, it weighed only approximately 12 kg as an adult.<\/p>\n Additionally, the discovery is unique in that the fossil provides a nearly intact skull, which is extremely rare for this particular family of dinosaurs.<\/p>\n Upon completing its first full skull, researchers noted that the structure of the head contained differences regarding the positioning of the head bones and jaw bones compared to other dinosaurs.<\/p>\n <\/p>\n <\/p>\n CT scans conducted on the skull showed that part of the roof of the dinosaur’s mouth, or palate, curved downward into the oral cavity.<\/p>\n Those structures supported muscles involved in chewing. This changed the movement from an upward-and-downward pattern to a side-to-side pattern.<\/p>\n While this type of arrangement was uncommon among non-bird dinosaurs, it appeared to be linked to a specialized<\/strong> feeding strategy.<\/p>\n As researchers pondered what types of food would require such an adaptation, comparisons to modern-day birds became useful.<\/p>\n In fact, researchers determined that the arrangements and configurations of the muscles resemble those used by certain types of fruit-eating parrots<\/a>, a finding detailed in Nature Communications.<\/p>\n Similar to those parrots, Infernogallus<\/em> is believed to have possessed the ability to crush soft foods using extensive mastication before consuming them<\/strong>.<\/p>\n Complex ridges and grooves located within the beak area likely functioned as a means to break down food during the process of chewing.<\/p>\n Evidence collected by researchers led them to conclude that the skull was particularly well-suited for breaking down fleshy fruits and avoiding the seeds associated with them. The findings were detailed in Nature Communications<\/em><\/a>.<\/p>\n According to information released by the Royal Ontario Museum<\/a>, flowering plants and their fruits diversified greatly during the Late Cretaceous period.<\/p>\n At almost the same time that flowering plants began to produce more fruit, caenagnathids underwent their greatest diversification<\/strong>.<\/p>\n These events suggest that new food sources may have played a major role in shaping evolutionary changes among dinosaurs.<\/p>\n If Infernogallus<\/em> indeed obtained all or most of its nutrition through eating fruit, then its significance goes beyond just a nutritional aspect.<\/p>\n Fruit-eating animals play critical roles in dispersing seeds<\/strong> away from parent plants and depositing them elsewhere.<\/p>\n The discovery of Infernogallus<\/em> presents a possible scenario where some dinosaurs performed similar functions for plant reproduction.<\/p>\n However, it will allow researchers to consider additional ways in which dinosaur communities<\/a> interacted with each other in terms of food webs.<\/p>\n Rather than merely consuming plants, some dinosaurs may have participated in interactions with plants that shaped community composition.<\/p>\n The discovery further emphasizes how much still remains unknown about how dinosaurs lived their lives.<\/p>\n Despite being discovered in one of the world’s best-studied fossil localities, Infernogallus<\/em> suggests the fossil record may still contain undiscovered dietary and behavioral specializations.<\/p>\n For several decades, discussions of dinosaur diversity have largely focused on how many species existed<\/strong>. Infernogallus<\/em> highlights a different possibility.<\/p>\n Some dinosaurs may have occupied ecological roles<\/a> that scientists did not know existed.<\/p>\n If a small fruit-eating dinosaur could remain hidden in such a well-studied ecosystem, other specialized lifestyles may still be waiting to be discovered.<\/p>\n","protected":false},"excerpt":{"rendered":" Most of the dinosaurs that we know today fall under one of two groups, meat-eaters and plant-eaters.
