TERQUEMIA (DENTITERQUEMIA) EUDESDESLONGCHAMPSI NEW SUBGENUS AND SPECIES, AN INTERESTING CEMENTING BIVALVE FROM THE LOWER JURASSIC OF THE WESTERN CARPATHIANS (SLOVAKIA)
|
ABSTRACT-
Based on well-preserved material from the Sinemurian of the western Carpathians, the new subgenus Terquemia (Dentiterquemia) is proposed, which is presently represented only by its type species T. (Dentiterquemia) eudesdeslongchampsi n. sp. Dentiterquemia is separated from Terquemia sensu stricto by a series of denticles along the hinge margin and corresponding, chevronlike ridges on the ligament area. The combination of hinge teeth with a cementing habit is interpreted as a ...

EVOLUTIONARY IMPLICATIONS OF A DUPLIVINCULAR LIGAMENT IN THE CARBONIFEROUS PINNID PTERONITES (MOLLUSCA, BIVALVIA, PTERIOMORPHIA)
Journal of Paleontology
; MODERN PINNOIDEANS, or "pen shells," are shallowly to deeply endobyssate, equivalved, edentulous, ham-shaped bivalves with a single, slightly submerged, opisthodetic ligament. Malacologists have generally regarded pinnids as closely related to the pterioid superfamily Pterioidea, especially its

TAXONOMY AND PHYLOGENY OF THE TRIASSIC BIVALVE FAMILIES MYSIDIELLIDAE COX, 1964 AND HEALEYIDAE NEW FAMILY
Journal of Paleontology
; ABSTRACT- The Mysidiellidae are morphologically isolated among Triassic bivalves but share important characters with Late Paleozoic Ambonychioidea. Apart from a great similarity in the general shape of the shell, the most primitive mysidiellid genus Promysidiella resembles ambonychioids in the

Bivalve systematics during the 20th century
Journal of Paleontology
; ABSTRACT-Over the past 75 years, the higher-level taxonomy of bivalves has received less attention than that of their fellow molluscs, gastropods. The publication of the bivalve volumes of the Treatise on Invertebrate Paleontology in 1969 was not followed by an explosion of study into the evolution
