The discovery of the olinguito is the first carnivore species to be found in the Western Hemisphere in over 35 years. The animal was discovered in cloud forests of Colombia and Ecuador through a combination of DNA testing, museum specimens, and field expeditions.
The discovery of the olinguito reveals that the world is not yet completely explored, with many species still unknown to science. The team's findings also highlight the critical need to protect the cloud forests of Ecuador and Colombia, which are under threat from human development.
A new analysis of ostriches suggests that sauropod neck flexibility was probably lower than previously estimated due to the impact of soft tissues like muscle and cartilage. This reduced flexibility may have restricted the range of foods these dinosaurs could reach, leading to more active foraging.
A new study published in Nature reveals that at least a few non-avian dinosaurs had brains as large or larger than those of Archaeopteryx, indicating they may have had the neurological hardwiring necessary for flight. This challenges the idea that Archaeopteryx was uniquely transitional between feathered dinosaurs and modern birds.
