 Caron and Jackson used computer software to simulate the numbers of species that would be found if smaller numbers of specimens were included , and found that the number of species " discovered " kept increasing as the number of specimens increased , rather than reaching a plateau . This suggests that Burgess Shale probably still contains as @-@ yet undiscovered species , although probably very rare ones . Some recently discovered species , known in 2008 only by nicknames like " woolly bear " and " Siamese lantern " are familiar to the collecting teams , but have yet to be formally described and named . The team also nicknamed another discovery as " Creeposaurus " , and in 2010 this animal was described and formally named Herpetogaster .
