1. The pre-acetabular portion of the pubis, esp. in Dinosaurs.
1888Rolleston & Jackson Anim. Life 65 This process appears to be the homologue of the prae-pubis (so-called) in the Stegosauria and Ornithopoda among Deinosauria. 1895Syd. Soc. Lex., Prepubes. 1896Newton Dict. Birds 862 The..anterior process of the os pubis, often called the pectineal,..is the element which in Dinosaurs is described as the ‘præpubis’, while in recent Reptiles it is represented by the pubis proper. 1956A. S. Romer Osteol. Reptiles vii. 328 In this case [sc. the pterosaur skeleton] the majority opinion is that the true pubis is included in the plate and that this anterior element is a neomorph, a prepubis.
2. = epipubis.
1931G. K. Noble Biol. Amphibia x. 240 A prepubis may have been a primitive character of modern Amphibia. 1969Nature 14 June 1091/1 Here I report the presence of the so-called marsupial bone (praepubis or epipubis) in the skeleton of K[ryptobaatar] dashzevegi. This bone has never before been found in fossil Multituberculata material. 1975Nature 26 June 698/1 Marsupial bones (epipubes, prepubes) occur in Marsupialia, Monotremata and have also been found in Cretaceous Multituberculata. |
