This is the last of four specimens of this amazingly well preserved
species that I have available for purchase. It comes from one of
the world’ foremost decapod collections. To begin, this is
not a composite. It is situated exactly where it died; painstakingly
curated from the sandy matrix which entombed it. Notice the unusual
look of this visually stunning genus. The full carapace, both claws,
mouthparts, and many of the legs are present.
is a family of unusual crabs, taken by most scientists to be quite
primitive. These animals closely resemble the (unrelated) mole crabs,
due to parallel evolution or evolutionary relay. In both groups,
the claws are modified into tools for digging, and the body is a
rounded shape that is easy to bury in sand. Unlike most other true
crabs, the abdomens of raninids are not curled under the cephalothorax.

this Ranilia species.
2008 and 2009 I had the unique privilege of purchasing two large
lots from a most important collection. The collector had painstakingly
accumulated a superb group of decapods, echinoderms and other fossils
during a twenty-year period. The vast majority of the specimens
came from self-collecting, academic resources, trading, and selected
purchases. Very few of fossils came from the normal channels of
trade shows and commercial internet resources. Any specimen presented
under this introductory paragraph will generally be a superior collector
grade fossil; be it of rarity, preservation, or, both.
