Abstract It recently has been claimed that sloths (Mammalia: Pilosa: Folivora) possess unique adhesions of their visceral organs that were considered to represent intracoelomic adaptations related to maximizing ventilatory efficiency in animals that hang vertically suspended (i.e. with their heads facing downwards) in trees. We examined the visceral anatomy in the brown-throated three-toed sloth ( Bradypus variegatus ) and compared our results to a number of historical anatomical references, alm...

The embryonic development of parabronchi occurs mainly during the second half of incubation in precocious birds, which makes this phase sensitive to possible morphological modifications induced by O 2 supply limitation. Thus, we hypothesized that hypoxia during the embryonic phase of parabronchial development induces morphological changes that remain after hatching. To test this hypothesis, chicken embryos were incubated entirely (21 days) under normoxia or partially under hypoxia (15% O 2 durin...

Air sacs are an important component of the avian respiratory system, and corresponding structures also were crucial for the evolution of sauropod dinosaur gigantism. Inferring the presence of air sacs in fossils so far is restricted to bones preserving internal pneumatic cavities and foramina as osteological correlates. We here present bone histological correlates for air sacs as a new potential identification tool for these elements of the respiratory system. The analysis of several avian and n...

Abstract Recently, 2 studies almost simultaneously described the same previously unrecognized species of semiaquatic Southeast Asian snail-eating turtle (Testudines: Geoemydidae: Malayemys Lindholm 1931): Malayemys khoratensis Ihlow et al. 2016 and M. isan Sumontha et al. 2016. In order to determine the valid name for the species in question, we performed a comprehensive bibliographical analysis of both underlying publications. We come to the conclusion that M. khoratensis is the older available...

The coelacanth, Latimeria chalumnae Smith, 1939 [1] (Sarcopterygii: Actinistia), together with the closely related L. menadoensis Pouyaud et al ., 1999 [2], remains the only living representative of one of the most basally-branching primary radiations of lobe-finned fishes (Sarcopterygii). Even though extant species cannot be considered ‘primitive’ due to the inherent logic of phylogenetic theory, the coelacanth nonetheless is invaluable for understanding evolutionary transformations in basal sa...

Summary In a recent report in Current Biology , Xing and colleagues [1] present a small fragment of a vertebrate tail preserved in amber that bears integumentary appendages (DIP-V-15103, Dexu Institute of Paleontology, Chaozhou, China; Figure 1). Following several analyses using cutting-edge technology the authors conclude that: the tail belongs to a non-avian theropod dinosaur (non-avialan according to the authors, but non-avian used synonymously here); the dinosaur most likely was a member of ...

The origin of the diaphragm remains a poorly understood yet crucial step in the evolution of terrestrial vertebrates, as this unique structure serves as the main respiratory motor for mammals. Here, we analyze the paleobiology and the respiratory apparatus of one of the oldest lineages of mammal-like reptiles: the Caseidae. Combining quantitative bone histology and functional morphological and physiological modeling approaches, we deduce a scenario in which an auxiliary ventilatory structure was...
