Colossal Biosciences Inc. is an American biotechnology and genetic engineering company working to de-extinct several extinct animals, including the woolly mammoth, the Tasmanian tiger, the northern white rhinoceros, the dire wolf, and the dodo.[1][3][4][5][6][7] In 2023, it stated that it wants to have woolly mammoth hybrid calves by 2028, and wants to reintroduce them to the Arctic tundra habitat.[8] Likewise, it launched the Tasmanian Thylacine Advisory Committee, a thylacine research project to release Tasmanian tiger joeys back to their original Tasmanian and broader Australian habitat after a period of observation in captivity.[9]

The company develops genetic engineering and reproductive technology for conservation biology. It was founded in 2021 by Harvard geneticist George Church and billionaire entrepreneur Ben Lamm.[3] It is based in Dallas, Texas.[10][11]
