The Anatomical Record, EarlyView.The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

ONTOGENETIC APPROACH IN NATURAL SCIENCES [PDF]
Минералогия, 2016 The knowledge of ontogenesis (evolution of life) of the solid matter allows predictions of different scientific models. An ontogenetic approach is a heuristic direction of science, because it considers the change in mineral body in time of their origin ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena
The Anatomical Record, EarlyView.Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Early evolution of the gular musculature and its innervation in ray‐finned fishes
The Anatomical Record, EarlyView.Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

The Anatomical Record, EarlyView.Abstract Studies of Upper Cretaceous deposits in North America have provided invaluable insights into the continental ecosystems of this time. Theropod (Saurischia, Dinosauria) pedal phalanges are commonplace in these deposits but can be difficult to identify at a finer taxonomic resolution.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.
