A monograph of the Cretaceous Lamellibranchia of England / by Henry Woods.

Abstract

Shell moderately convex, oval or subtriangular ; height a little greater than length ; outline rounded, except the antero-dorsal margin, which is nearly straight and rather long. Apical angle from 105 to 110. Umbones rather small, close together. Anterior area slightly depressed, with small radial ribs. Anterior ears small ; posterior larger, with growth-lines and faint radial ribs.

Well‐developed muscle attachments in British Albian inoceramids (Inoceramidae, Bivalvia): implications for inoceramid palaeobiology, evolution and taxonomy

“…Well‐developed umbonal muscle scars in a phosphatized left valve of Gnesioceramus anglicus (Woods) ( NHMUK PIMB 1303), Gault Clay Formation (Albian), cristatum Zone, Greatness Lane, Sevenoaks (Kent). A, wedge‐like, lobed structures protruding from the posterior umbonal region.…”

“…Muscle scars in phosphatized Gnesioceramus anglicus (Woods). A–C, OUM K5316, Gault Clay Formation (Albian), spathi Subzone, Greatness Lane, Sevenoaks (Kent).…”

“…Ultrastructural components of the biomineralized sheet structures of Gnesioceramus anglicus (Woods) ( OUM K13052), Gault Clay Formation (Albian), daviesi Subzone, Folkestone (Kent). Ultrastructural components of the mineralized posterior lobe.…”

“…The arrangement, size and general character of the inoceramid musculature are evidenced by muscle scars on the shell interior, and give a record of the nature of the ‘anatomy’ of the organism within the valves. Our research considers inoceramid musculature with specific reference to evidence of well‐developed muscle attachment scars in Gnesioceramus anglicus (Woods, 1911) from the Gault Clay Formation (Albian) in the United Kingdom.…”

The fossil record of Limopsis (Bivalvia: Limopsidae) in Antarctica and the southern high latitudes

“…Hallam (1976, 1977) described the radiation of Limopsis in the Jurassic, but his records were based on L. minima and thus are disregarded. Oliver (1981) believed that the first truly recognizable Limopsis sensu stricto specimens, assigned to L. albiensis (Woods, 1899), were from the Early Cretaceous (Albian, around 112 Ma) of England (Woods 1899). There is also evidence that Limopsis occurred uncommonly in late Early Cretaceous rocks of New Zealand, although species are unnamed (Speden 1975; Moore and Speden 1984).…”
