A fascinating fossil found in the Glen Rose Formation of Texas, specifically a type of bivalve referred to as a "Texas heart clam" in popular terms. This fossil exhibits a heart-shaped or rounded form, which is characteristic of its classification within the genus Cucullaea.
These fossils are typically preserved as internal casts, where the original shell has dissolved, and the surrounding sediment has filled the space, leaving a mold of the shell's interior. This method of preservation provides valuable insights into the geological history of the region and the species that once inhabited it.
