Cryptoprocta spelea, also known as the giant fossa, is an extinct species of carnivore from Madagascar in the family Eupleridae, which is most closely related to the mongooses and includes all Malagasy carnivorans. It was first described in 1902, and in 1935 was recognized as a separate species from its closest relative, the living fossa (Cryptoprocta ferox). C. spelea is larger than the fossa, but otherwise similar. The two have not always been accepted as distinct species. When and how the larger form went extinct is unknown; there is some anecdotal evidence, including reports of very large fossas, that there is more than one surviving species.

The species is known from subfossil bones found in a variety of caves in northern, western, southern, and central Madagascar. In some sites, it occurs with remains of C. ferox, but there is no evidence that the two lived at the same time. Living species of comparably sized, related carnivores in other regions manage to coexist, suggesting that the same may have happened with both C. spelea and C. ferox. C. spelea would have been able to prey on larger animals than its smaller relative could have, including the recently extinct giant lemurs. (see more...)

Mary Anning (1799 – 1847) was a British fossil collector, dealer, and palaeontologist who became known around the world for important finds she made in Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis in the county of Dorset in Southwest England. Her work contributed to fundamental changes in scientific thinking about prehistoric life and the history of the Earth.

Mary Anning searched for fossils in the area's Blue Lias cliffs. Her discoveries included the first ichthyosaur skeleton correctly identified; the first two plesiosaur skeletons found; the first pterosaur skeleton located outside Germany; and important fish fossils. Her observations played a key role in the discovery that coprolites, known as bezoar stones at the time, were fossilised faeces. She also discovered that belemnite fossils contained fossilised ink sacs like those of modern cephalopods.

Anning did not fully participate in the scientific community of 19th-century Britain, who were mostly Anglican gentlemen. She struggled financially for much of her life. Her family was poor, and her father, a cabinetmaker, died when she was eleven. She became well known in geological circles in Britain, Europe, and America. Nonetheless, as a woman, she was not eligible to join the Geological Society of London and she did not always receive full credit for her scientific contributions. After her death in 1847, her unusual life story attracted increasing interest. (see more...)
