The first spiders  evolved  from crab-like Chelicerate ancestors over 400 million years ago. Today, there are more than 45.000 described spider species within the  phylum of arthropods.  Anatomically, spiders differ from other Arthropods in that the usual body segments are fused into two parts, the cephalothorax  and abdomen, and joined by a small, cylindrical pedicel. Unlike insects, spiders do not have antennae. This interesting specimen was trapped at least 20 million years ago in an amber stone excavated in La Bucara Mine in the Winter of 2014.
