Thermoluminescence dating of calcite shells in the pectinidae family

Quaternary Science Reviews, 1992
Abstract Previously we investigated the thermoluminescence (TL) of a calcite shell, Pectinidae Pecten (Notovola) albicans (Schroter) (abbreviated to albicans), and we found that TL dating was possible for fossil calcite shells of albicans from 5 × 10 5 years ago to the present.

The mitochondrial genome of the scallopMimachlamys senatoria(Bivalvia, Pectinidae)

Mitochondrial DNA, 2013
The mitochondrial (mt) genome of the scallop Mimachlamys senatoria (17,383 bp), an economically and ecologically important bivalve, was newly sequenced and annotated. Comparative analyses between M. senatoria and its congeneric sister species M. nobilis revealed three new findings: (1) M.

PHYLOGENETIC RELATIONSHIPS AMONG NINE SCALLOP SPECIES (BIVALVIA: PECTINIDAE) INFERRED FROM NUCLEOTIDE SEQUENCES OF ONE MITOCHONDRIAL AND THREE NUCLEAR GENE REGIONS

Journal of Shellfish Research, 2007
Current knowledge of the evolutionary relationships among scallop species (Mollusca: Bivalvia: Pectinidae) in the Indo-Pacific region is rather scanty.

Rubber-Like Properties of the Inner Hinge-Ligament of Pectinidae

Journal of Experimental Biology, 1966
ABSTRACT The inner hinge-ligament of Pectinidae (Lamellibranchiata) is an elastic block of amorphous cross-linked protein, plasticized with water. It acts as a compression spring, and is the antagonist of the shell adductor muscle. Its elasticity is shown to be rubber-like, in that the elastic restoring force is mainly due to entropy ...

Mclearnia Crickmay, 1930 (Bivalvia: Pectinidae)

Journal of Paleontology, 1986
In revising the subgenus Mclearnia Crickmay (1930), Kelly, Dhondt and Zakharov (1984) recommended that the spelling of the subgenus and species should be emended to Maclearnia maclearni. The latter authors had followed Recommendation III 21(a) of the International Code of Zoological Nomenclature (Stoll, 1964, p.

Some Atlantic Coast Tertiary Pectinidae

American Midland Naturalist, 1934
P1. 25, fig. 1. Description: Shell very thin, equilateral, suborbicular. A single strong radial cord extends nearly to the beak anteriorly and another posteriorly; three weaker, equally spaced cords lie between the secondary cords and become obsolete 2 mm. from the margin of the disk.

Level of Acceptability of Scallop (Pectinidae) Kropek

Business Fora: Business and Allied Industries International Journal
This experimental study aimed to determine the acceptability of scallop kropek as to aroma, color, flavor, texture and general acceptability as well as its acceptability in three formulations made up of 1/4 cup scallop paste and ¾ cup tapioca flour (Formulation A); ½ cup scallop paste and ½ cup tapioca flour (Formulation B; and, ¾ cup scallop paste and

Shell characteristics of the family pectinidae as environmental indicators

1969
Many characteristics of bivalve shells are related to environmental rather than hereditary conditions. If these acquired characteristics could be recognized and interpreted in fossil shells they would be of considerable significance in paleoecology.

Swimming in Amusium pleuronectes (Bivahia: Pectinidae)*

Journal of Zoology, 1980
Aspects of functional design in the Pectinidae have led scientists to speculate that scallops of the Amusium group (Hertlein, 1969) are among the best swimmers. This study of Amusium pleuronectes confirms this view, with average swimming speeds ranging from 37–45 cm/second. A speed of 73 cm/second was recorded from one scallop.
