This suggests that Burgess Shale probably still contains as-yet undiscovered species, although probably very rare ones.[1] 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.[13] The team also nicknamed another discovery as "Creeposaurus", and in 2010 this animal was described and formally named Herpetogaster.[32]
