This is the type genus of the family. Biological evolution is supported by the fossil record because it shows through observable facts how animals are related, their similarities and differences to one another, and how they change over time. The coarseness and rib spacing of Vertipectens has been slowly evolving since the early and Mid-Miocene, so they have been around for at least 16 million years, maybe up to 20 million years. Calico and bay scallops are bivalve (two-shells) molluscs in the Pectinidae family and are similar in both anatomy and life history. Valve color and shell morphometry distinguish calico scallops from related species. Policies are also needed to electrify existing buildings, and gas bans alone aren't the right solution, given the cost of retrofits, Bataille said. An expert from Switzerland and one from Australia eventually also joined the research team. Fossil Scallop Among the many shells are beautiful fossil scallops, including forms like this called Pecten or Chesapecten. It is split into Quaternary Period, Pecten gibbus, and Tertiary Period, Calyptraphorus velatus. "It confirmed that the Miguasha site is really exceptional," she said. 1 / 13.
