Thomisidae (Crab Spider)

Age : Eocene ( 49 Ma)
Formation : Parachute Creek Member / Green River Formation
Locality : Hawes Quarry, Rio Blanco, Colorado

Spider : 0.5 x 0.4 cm

Crab spider is a common name applied loosely to many species of spiders, but most nearly consistently to members of the family Thomisidae. Among the Thomisidae it refers most often to the familiar species of "flower crab spiders", though not all members of the family are limited to ambush hunting in flowers.

Rationalisation for the name crab spider is generally subjective and anecdotal. It is commonly said to refer to a fancied resemblance to crabs, or to the way such spiders hold their two front pairs of legs, or their ability to scuttle sideways or backwards. Some spiders so called have bodies that are flattened and angular. At all events, the Thomisidae are the family most generally referred to as "crab spiders".

Description

Details

The Green River Formation is famous worldwide for its fossil fish and other associated fauna (reptiles, birds, mammals, & plants). The Green River Fm. also provides us a rare snapshot glimpse into life 49 million years ago.

The preservation of the fossil insects in the Hawes Quarry are just spectacular, some good enough to allow not only identification to family and subfamily, but will sometimes show color patterns, wing venation, and sex-related characters.

This fossil specimen was collected by William Hawes, from his quarry, the Hawes Quarry, in Rio Blanco County, Colorado. The Hawes Quarry has produced some of the most amazingly beautiful insect fossils from the Green River Fm. and these represent the hand selected, choice picks, from Hawes years of collecting in the mountains of Colorado.

Specimen will come with an identification card.
