Homo heidelbergensis: The Tool to Our Success [PDF]

open access: yes, 2016
Homo heidelbergensis, a physiological variant of the species Homo sapien, is an extinct species that existed in both Europe and parts of Asia from 700,000 years ago to roughly 300,000 years ago (carbon dating). This “subspecies” of Homo sapiens, as it is

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Case report: Radiopaque mandibular lesions in three dogs

open access: yesFrontiers in Veterinary Science
Radiopaque lesions of the mandible are occasional findings in dental radiographs in dogs. The different diagnoses of densely sclerotic lesions in humans include odontoma, idiopathic osteosclerosis, condensing osteitis, hypercementosis, osteoma ...

Relational Reasoning Network (RRN) for Anatomical Landmarking

open access: yes, 2019
Accurately identifying anatomical landmarks is a crucial step in deformation analysis and surgical planning for craniomaxillofacial (CMF) bones. Available methods require segmentation of the object of interest for precise landmarking.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

open access: yesThe Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Description of the larva of Phyllopetalia apollo Selys and redescription of that of Hypopetalia pestilens Mclachlan (Anisoptera: Austropetalidae) [PDF]

open access: yes, 2009
The P. apollo larva is described for the first time and the larva of H. pestilens is redescribed.These are the first records of these spp. for Argentina and for the easternslope of the Andes. In order to determine the larval instars, length of inner wing

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
