Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...
