COMPUTATIONAL FLUID DYNAMICS CONFIRMS DRAG REDUCTION ASSOCIATED WITH TRILOBITE QUEUING BEHAVIOUR

期刊: PALAEONTOLOGY, 2021; 64 (5)

Queuing behaviour has been documented in marine arthropods from Cambrian to modern oceans. It was previously hypothesized that this behaviour provided......

Go large or go conical: allometric trajectory of an early Cambrian acrotretide brachiopod

期刊: PALAEONTOLOGY, 2021; 64 (5)

Acrotretides are extinct micromorphic brachiopods that exhibited considerable morphological variation during their rapid evolution in the early Palaeo......

Testing for a dietary shift in the Early Cretaceous ceratopsian dinosaur Psittacosaurus lujiatunensis

期刊: PALAEONTOLOGY, ; ()

Many dinosaurs may have shown ecological differentiation between hatchlings and adults, possibly because of the great size differential. The basal cer......

Sporopollenin chemistry and its durability in the geological record: an integration of extant and fossil chemical data across the seed plants

期刊: PALAEONTOLOGY, 2021; 64 (2)

Sporopollenin is a highly resistant biopolymer that forms the outer wall of pollen and spores (sporomorphs). Recent research into sporopollenin chemis......

Uninterrupted growth in a non-polar hadrosaur explains the gigantism among duck-billed dinosaurs

期刊: PALAEONTOLOGY, 2020; 63 (4)

Duck-billed dinosaurs (Hadrosauridae) were the most common ornithopods of the Late Cretaceous. Second only to sauropods and in many cases exceeding th......

Algal affinity and possible life cycle of the early Cambrian acritarchYurtusia uniformisfrom South China

期刊: PALAEONTOLOGY, 2020; 63 (6)

Abundant, well-preserved specimens of spheroidal organic-walled microfossilYurtusia uniformisare reported from the basal Cambrian Yanjiahe Formation i......

Experimental investigation of insect deposition in lentic environments and implications for formation of Konservat Lagerstatten

期刊: PALAEONTOLOGY, 2020; 63 (4)

Terrestrial insects are often remarkably well preserved in lacustrine Konservat Lagerstatten. However, the assumption that carcasses should sink fast ......

The Collins' monster, a spinous suspension-feeding lobopodian from the Cambrian Burgess Shale of British Columbia

期刊: PALAEONTOLOGY, 2020; 63 (6)

Lobopodians, a paraphyletic group of rare but morphologically diverse Palaeozoic vermiform animals bearing metameric appendages, are key to the origin......

The evolution of the modern avian digestive system: insights from paravian fossils from the Yanliao and Jehol biotas

期刊: PALAEONTOLOGY, 2020; 63 (1)

The avian digestive system, like other aspects of avian biology, is highly modified relative to other reptiles. Together these modifications have impa......

Periodic shell decollation as an ecology-driven strategy in the early Cambrian Cupitheca

期刊: PALAEONTOLOGY, 0; ()

Shell decollation is a growth strategy that has been adopted by a number of invertebrate taxa to offset the metabolic and ecological disadvantages of ......

Ecological stasis in Spinicaudata (Crustacea, Branchiopoda)? Early Cretaceous clam shrimp of the Yixian Formation of north-east China occupied a broader realized ecological niche than extant members of the group

期刊: PALAEONTOLOGY, 2019; 62 (3)

The palaeoecology of Spinicaudata, the dominant group of benthic invertebrates in many pre-Cenozoic freshwater environments, remains poorly understood......

Tooth microwear and occlusal modes of euharamiyidans from the Jurassic Yanliao Biota reveal mosaic tooth evolution in Mesozoic allotherian mammals

期刊: PALAEONTOLOGY, 2019; 62 (4)

'Haramiyidans' are extinct mammaliaforms often clustered with Multituberculata as Allotheria, and with a fossil record extending from the Upper Triass......

Homologous shell microstructures in Cambrian hyoliths and molluscs

期刊: PALAEONTOLOGY, 2019; 62 (4)

Hyoliths were among the earliest biomineralizing metazoans in Palaeozoic marine environments. They have been known for two centuries and widely assign......

Apparatus architecture of the conodont Nicoraella kockeli (Gondolelloidea, Prioniodinina) constrains functional interpretations

期刊: PALAEONTOLOGY, 2019; 62 (5)

We reconstruct the apparatus architecture of the gondollelid conodont Nicoraella kockeli based on fused clusters from the early Middle Triassic (middl......
