Here is a spectacular fossil crab. This is Cancer arancana from the Oligocene of Chile. This crab was found in a very hard, dense concretion. Half of the concretion has been painstakingly removed to reveal this wonderful fossil. Preparation of a specimen like this is quite laborious, to say the least. The crab is 3-dimensionally preserved and exhibits fine detail. The carapace and BOTH claws of the crab are beautifully displayed. All eight legs are even preserved. The fossil has good natural color and contrast. The crustacean is well centered in the large concretion. This is simply an excellent specimen of this fossil crab from South America.
