Vulpes qiuzhudingi is an extinct species of fox that lived during the Neogene period in the Himalayas. [2] It was primarily carnivorous. [3] The fossils, dating from the Pliocene epoch between 5.08 and 3.60 million years ago, were discovered in the Zanda Basin and Kunlun Mountains of Tibet.
Theropod dinosaurs such as Tyrannosaurus rex that existed during the late Cretaceous, although not mammals, were obligate carnivores. Large hypercarnivores evolved frequently in the fossil record, often in response to an ecological opportunity afforded by the decline or extinction of previously dominant hypercarnivorous taxa.
The small dinosaur eggs, discovered in 2021, represent an entirely new species, due to their unique features. 80-million-year-old dinosaur eggs dug up in China are the smallest ever found Skip to ...
In the UK, the term "weasel" usually refers to the smallest species, the least weasel (M. nivalis), [1] the smallest carnivoran species. [ 2 ] Least weasels vary in length from 173 to 217 mm ( 6 + 3 ⁄ 4 to 8 + 1 ⁄ 2 in), [ 3 ] females being smaller than the males, and usually have red or brown upper coats and white bellies; some populations ...
