| Caption: | A fossil specimen of Hippopodium ponderosum J. Sowerby. A fossil bivalve. (Mollusca, Bivalvia.) Raasay, Invernessshire, Scotland. |
| Description: | Hippopodium ponderosum is from the Lower Jurassic, Lower Lias, raricostatum zone of Raasay; a series of marine shales that consisted of the lower Broadford Beds composed of limestone and shales and the upper Pabba Shales consisting of sandy micaceous shales. British Geological Survey Biostratigraphy Collection number GSE 2296. Like Cardinia and Astarte, Hippopodium was a member of the muddy sand community and an infaunal (burrowing), suspension-feeding bivalve. Bivalves first appeared in the Mid Cambrian and have evolved to live in many environments, attached to rock surfaces, burrowing in soft sediment or boring in rock. Some live on the sea floor and are capable of swimming. |
