The living members of the Argopecten gibbus stock include the bay and calico scallops, Argopecten irradians (Lamarck) and A. gibbus (Linné), both common in the western Atlantic and Gulf of Mexico; the less common A. nucleus (Born) of the Caribbean, southern Gulf of Mexico, Antilles, and southeastern Florida; and the common A. circularis (Sowerby) and A. purpuratus (Lamarck) of the … The living members of the Argopecten gibbus stock include the bay and calico scallops, Argopecten irradians (Lamarck) and A. gibbus (Linné), both common in the western Atlantic and Gulf of Mexico; the less common A. nucleus (Born) of the Caribbean, southern Gulf of Mexico, Antilles, and southeastern Florida; and the common A. circularis (Sowerby) and A. purpuratus (Lamarck) of the eastern Pacific. American Fisheries Society Special Publication 16. vii + 277. Synonymns and other Related Names: No related names recorded. The primitive bay scallop was apparently unable to reach the Pacific, but the open-marine species seems to have given rise to both the Pacific A. purpuratus and the Atlantic calico scallop, A. gibbus. Many of these journals are the leading academic publications in their fields and together they form one of the most valuable and comprehensive bodies of research available today. 71 million years ago.

This species was once the basis of an important fishery, but in recent years catches have been low. © 1969 Cambridge University Press off Cape Canaveral. Pecten (Chlamys) gibbus L. var. Pecten gibbus. With regard to nomenclature, the name Argopecten is shown to be a senior synonym of Plagioctenium; the generic name Aequipecten is rejected for American species related to Argopecten gibbus; and it is concluded that the generic name Chlamys, sensu lato, is better applied as the subfamily name Chlamydinae. This species evolved phyletically through A. nicholsi (Gardner) of the Shoal River Formation and A. choctawhatcheensis (Mansfield) of the Arca Faunizone into A. comparilis (Tuomey & Holmes) of the upper Miocene (Tamiami, Pinecrest, Duplin, and Yorktown Formations). Pecten gibbus fossils are similar to sea shells we might find today. Bivalvia (Mollusca) of the Gulf of Mexico, Pp. meridionalis, Pecten Tate, 1887 = Pecten fumatus merriami, Pecten Arnold, 1906 = Patinopecten caurinus midwayensis, Chlamys Habe & Okutani, 1968 = Laevichlamys cuneata ; The bivalve shells don't really do any harm to the environment.

In certain features of morphology, the A. gibbus lineage is convergent on the A. eboreus lineage, indicating that the extinct species may also have been restricted to open marine waters. Fossils are the preserved remains or traces of animals, plants and other organisms from the past. It includes longer systematic monographs and symposia, which supplement regular issues of the Journal.

A. comparilis was apparently broadly adapted and widely distributed, living in bays, sounds, and open marine waters in the western Atlantic, Gulf of Mexico, and Caribbean and probably extending through seaway passages to the Pacific, where it gave rise phyletically to A. circularis.

GET STARTED. EMUSIC TOKEN. Philippi, R. A. Pecten gibbus fossils appear extremely similar to the seashells that we often find lying on the beaches, which show how the evolution of shell started about 2 million years ago. Differences between samples were studied and evaluated by means of morphometric data consisting of 70 measurements and form ratios of the outline, ligamenture, and musculature of each valve. Remarks.

Argopecten gibbus Name Homonyms Pecten gibbus (Linnaeus, 1758) Bibliographic References. During the Pleistocene, A. nucleus, a tropical bay scallop, is inferred to have split from A. gibbus and to have become morphologically convergent on the true bay scallop, A. irradians. Because barrier islands seem to have played a key role in speciation within the stock, it would appear that evolutionary differences may have been caused by the active coastal tectonism of the Pacific side destroying such island barriers before genetic differences between inshore and offshore scallop populations could arise.

Explanation: They appears during Cretaceous period and Quaternary period which ranges from 70.6 to 0.0 million years old. A. eboreus, a common scallop on the eastern side of the Americas in the Miocene and Pliocene, represents a highly variable yet morphologically persistent lineage that neither split nor gave rise phyletically to other species and that became extinct during the early Pleistocene. Tropites, genus of extinct cephalopods (animals similar to the modern squid and octopus but with an external shell) found as fossils in marine rocks of the Late Triassic Period (from 230 to 208 million years ago). 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. Paleontologically, it is limited to an analysis of morphological variation among samples of fossil populations collected from upper Cenozoic strata (Alum Bluff Group of the middle Miocene through the Pleistocene) exposed on the Atlantic and Gulf Coastal Plains of the United States. The time span investigated is about 18 million years, according to the latest published scale of absolute time. Argopecten gibbus, the Atlantic calico scallop, is a species of medium sized edible marine bivalve mollusk in the family Pectinidae, the scallops.

By the end of the Miocene, on the eastern side of the Americas, this variable species had split, giving rise to a primitive bay scallop, A. anteamplicostatus (Mansfield), that, like the living bay scallop (its phyletic descendant), was probably ecologically restricted to the semienclosed waters of bays and sounds, and to another species, A. vicenarius (Conrad), probably restricted to open marine waters like the living calico scallop.
