First account of erectile tissue in an invertebrate animal the Octopus copulatory organ
THOMPSON, J.T.*; VOIGHT, J.R.; University of North Carolina; The Field Museum of Natural History: First account of erectile tissue in an invertebrate animal: the Octopus copulatory organ The most familiar examples of erectile tissue are the genitalia of mammals, notably the penis and clitoris. Among the soft-bodied invertebrates, erectile tissue is virtually unknown, even in […]
Constant function or random evolution changes in the apertural ornamentation of fusiform neogastropods since the Cretaceous
PRICE, RM; University of Chicago: Constant function or random evolution: changes in the apertural ornamentation of fusiform neogastropods since the Cretaceous Columellar folds, ridges visible on the inner lip of a gastropod’s aperture, are useful in distinguishing species, but the evolution of folds has hardly been considered even though they evolved in at least 6 […]
Archosaur jaw muscle homology and evolution extant data
HOLLIDAY, CH; WITMER, LM; Dept. of Biological Sciences, Ohio University; Dept. of Biomedical Sciences, Ohio University: Archosaur jaw muscle homology and evolution: extant data The jaw muscles of extant archosaurs have been well documented in numerous descriptive and functional studies. However, paraphyletic treatment of crocodilians and birds, poorly integrated descriptions of neighboring structures, and disparate […]
