The Carapace and Crustacean Evolution—Arebuttal
Journal of Crustacean Biology, 1984ABSTRACT Professor Dahl purports to overthrow the long-standing premise that the primitive malacostracan carapace extends freely from the back of the cephalon. If the premise were overthrown, a number of serious difficulties would develop in long accepted hypotheses concerned with evolution within the Malacostraca as well as with the affinities of ...

Phaeohyphomycosis of the Carapace in an Aldabra Tortoise (Geochelone gigantea)
Journal of Zoo and Wildlife Medicine, 2009An adult male Aldabra tortoise (Geochelone gigantea) presented with a deep flaking area of the carapace, and histologic examination of biopsies from this area revealed phaeohyphomycosis of the superficial keratinized layers. The disease progressed rapidly and spread to numerous sites on the carapace.

Early Cambrian Ostracode Larvae with a Univalved Carapace
Science, 1993Phosphatized univalves, recovered from the Lower Cambrian (∼530 million years old) Qiongzhusi Formation in southern China, are recognized as early instars belonging to bradoriid ostracodes whose later instars are bivalved. The univalved form is the primitive larval character for shell-secreting crustaceans, although most post-Cambrian ostracodes ...
