Integument. . . extant vx extinct
Have a look at this bizarre little beauty. . .

Seeing is of course believing and in the case of fossil specimens at least
half way to believing ( depending upon the source of academic
interpretation ). The point. . . if a creature like this were unknown to
science ( as this one was until just recently ), but instead an ancient
counterpart were discovered in a fine grain sediment in which detail was
nicely preserved, how difficult would it be for the scientific community to
accept such an anomaly with unexpected hirsute covering? Some might
interpret or discount the evidence within the slab as an occurance of
dendrites, collagen, etc. . . but who would willingly accept or expect a
creature of the deep to be shrouded as is the "Yeti crab". Do discoveries
like these make it easier when considering ( cladistics aside for the
moment ) phenomena like proto-feathers on dinosaurs? While the overwhelming
majority vertebrate paleontologists have readily embraced the shift in
thinking to feathered theropods, it seems hard to believe there is still a
vocal minority within the scientific community who stand in opposition of
the weight of evidence, especially in light of examples of evolutionary
diversity that populate our planet today. . . like"hairy crabs" ( who would
have thunk it? )
