Vertebrate Paleontology of the Cloverly Formation (Lower Cretaceous), II: Paleoecology
Journal of Vertebrate Paleontology, 2016 Vertebrate microfossil assemblages in terrestrial formations are a promising source of data on the structure of fossil metacommunities. However, the degree to which these deposits capture true, metacommunity-level samples is unknown.

Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, EarlyView.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Structural Color in Amber-Entombed Wasp: A Detailed Study Using NS-FDTD Simulations
IEEE AccessThe multilayer reflectors of insect epidermis can produce unique structural color through interactions with light. Many fossilized insects, like amber-entombed wasps, present structural colors. However, how this multilayer structure and structural colors

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Trabecular bone ontogeny of the human talus
The Anatomical Record, EarlyView.Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Mitochondrial phylogenomics supports a Carboniferous origin of Xenonomia
The European Zoological JournalPolyneoptera includes some of the best-known insect species, such as grasshoppers and cockroaches. While the evolutionary history of many Polyneoptera orders has been thoroughly explored, others have been partially overlooked.

The Anatomical Record, EarlyView.Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

The Anatomical Record, EarlyView.Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...
