Here is an unusual plate of echinoderms from the Cretaceous of Texas. This slab contains at least a dozen specimens of fossil brittlestars. Brittlestars are extremely uncommon in the fossil record. A multiple plate of fossil brittlestars is a very exciting find. Brittlestars have a large central disk with five long, thin, sinuous arms. These specimens retain the central disk and many of the very thin arms are well preserved. Several of the brittlestars are totally complete with all of the arms intact. Even the individual plates of the arms are clearly defined. The brittlestars have excellent, dark gray color and contrast nicely with the light grayish-tan matrix. The fossils are well presented on the natural plate of matrix. This is a very rare find of Cretaceous brittlestars from Texas.
