Fossil record
[edit | edit source]Whole specimens of Heliaster microbrachius have been found preserved in calcite-cemented quartz in Southwest Florida that dates to the Pliocene, 3.5 to 2.5 million years ago (Castilla et al. 2013). Today H. microbrachius is found only in the Pacific Ocean: on the coast of Panama, and Acapulco in Mexico. This suggests that greater connection between the two oceans gave the species a more extensive range in the past (Castilla et al. 2013).
