Propalaeocastor is a poorly known extinct genus of beavers (family Castoridae) from the early Oligocene of Europe and Asia. Recently described material of a new species of Propalaeocastor, P. irtyshensis, indicates the genus is probably the earliest known member of the subfamily Castorinae, [1] which includes all castorids more closely related ...Palaeocastor peninsulatus is a scratch-digger with few cranial adaptations to burrowing susceptible to change with maturity. Dental characters, however, are modified with wear and vary greatly ...

Martin and Bennett (1977) also found that their living-chambers had dips to their shafts of up to 43°, so a straight shaft incline angle (φ) could have assuredly also been up to at least 43°.

Therefore, other, more complex functions must play a role in determining ... Behavior. These lumpsuckers are solitary by nature and are usually found alone. Inefficient swimmers because of their spherical body and small fins, when disturbed, spiny lumpsuckers aimlessly change directions. They use rocks and seaweeds for hiding places. Adaptation. They rely on their excellent camouflage to avoid detection by predators.The cranial morphology of M. skinneri is primitive for Castoroidini and that of E. valentinensis is specialized for tooth−digging behavior as in the Nothodipoidini. A new genus, Temperocastor, is proposed for E. valentinensis based on its primitive morphology of the cheek teeth and derived cranial morphology.

Differential reinforcement relies on 2 primary components, providing reinforcement for desired behavior and withholding reinforcement for target behavior.Palaeocastor ('ancient beaver') is an extinct genus of beavers that lived in the North American Badlands during the late Oligocene period to early Miocene.
