The Skull of the Olinguito This video, fourth in the Shelf Life series, reveals how scientists in the field found the skull of a new species and identified it as the elusive olinguito. Thousands of new animal species are discovered every year, some living and some extinct. Researchers regularly make expeditions to the far-flung corners of the globe in search of new species, ranging from the single-celled organisms found in pools of volcanic sulfur (or even in your own stomach), to deep-sea organisms and larger animals like monkeys and birds.…

Armored Dinosaurs, Elaborate Nasal Passages

November 9, 2014September 4, 2017 Science Connecteddinosaurs, fossils, paleontology

Since paleontologists began using CT scans and 3D reconstructions of dinosaur remains, they have been able to tell us much more about dinosaurs than ever before. Now a new study shows that armor-plated dinosaurs (ankylosaurs) had the capacity to modify the temperature of the air they breathed using nasal passages shaped like “crazy straws.” We know that animals use strategies such as sweating, panting, and swimming to prevent their brains from overheating. However, the ankylosaur appears to have relied upon its long and winding nasal cavity to cool down, using…
