Extinction of taxa is difficult to detect, as a long gap without a sighting is not definitive. Some mammals declared as extinct may very well reappear. [1] For example, a study found that 36% of purported mammalian extinction had been resolved, while the rest either had validity issues (insufficient evidence) or had been rediscovered. [3]

Paleontologists at work at the dinosaur site of Lo Hueco (Cuenca, Spain). Vertebrate paleontology is the subfield of paleontology that seeks to discover, through the study of fossilized remains, the behavior, reproduction and appearance of extinct vertebrates (animals with vertebrae and their descendants).
The hypothesis further assumes decreases in vegetation due to climate change, but deglaciation doubled the habitable area of North America. Any vegetational changes that did occur failed to cause almost any extinctions of small vertebrates, and they are more narrowly distributed on average, which detractors cite as evidence against the hypothesis.
Despite the world's last captive thylacine dying in 1936, the secretive animal wasn't declared extinct until 1986. More recently in 2007 the Baiji dolphin , a rare river dolphin native to China ...
