The Anatomical Record, EarlyView.Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

The Anatomical Record, EarlyView.Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

The Anatomical Record, EarlyView.Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Multi‐Century Grindstone Quarrying at Brumby Yard, Queensland
Archaeology in Oceania, EarlyView.ABSTRACT The timing and duration of prehistoric quarrying is poorly understood within Australia, with limited ages available for quarries owing to the difficulties in dating these rock‐sediment constructions. We report the first multi‐sample, optically stimulated luminescence ages from quarry pits in Brumby Yard, an Aboriginal grindstone quarry ...
