 Description:
Among the world’s best-preserved crab fossils are those coming
from western Washington state. Generally, crabs quickly fall apart
after death, so for these crabs to be found is so fine a state of
preservation is a rarity. They must have been buried soon after death.
The crabs are found in concretions along the sides of creeks and beds
of local streams. Painstaking work and long hours are required to
prepare one as seen here.
This
Pulalius is an excellent example. Eight of ten appendages have been
preserved. Note the shiny dark brown color of the carapace and legs.
It is fully inflated, well-centered and 3D. |
