As of July 2016, the International Union for Conservation of Nature (IUCN) lists 395 extinct species, 206 possibly extinct species, 15 extinct in the wild species, 8 extinct subspecies, and 5 extinct in the wild subspecies of invertebrate. [1] [2]
As a result, some groups of invertebrates are not listed. [1] If an invertebrate animal is mentioned below using its common (vernacular) name, it is an extant (living) taxon, but if it is cited by its scientific genus, then it is typically an extinct invertebrate known only from the fossil record. [2]
Invertebrate species (IUCN, 2020.1) 17,646 extant species have been evaluated; 12,368 of those are fully assessed [a] 8024 are not threatened at present [b] 4328 to 9606 are threatened [c] 410 to 616 are extinct or extinct in the wild: 395 extinct (EX) species [d] 15 extinct in the wild (EW) 206 possibly extinct [CR(PE)] 0 possibly extinct in ...
All of these were described from fossils before later being found alive. [15] [16] [17] The fact that a living fossil is a surviving representative of an archaic lineage does not imply that it must retain all the "primitive" features (plesiomorphies) of its ancestral lineage. Although it is common to say that living fossils exhibit ...
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Saber-toothed cats of the extinct genus Homotherium lived across the globe during the Pliocene (5.3 million to 2.6 million years ago) and early Pleistocene (2.6 million to 11,700 years ago) epochs ...

They were once thought to be extinct but were rediscovered in 2001. ‘Tree lobsters’ — the rarest insects on Earth — are on exhibit at a US zoo. See them
