Morphology of the earliest reconstructable tetrapod Parmastega aelidae
TL;DR: Three-dimensionally preserved fossils of Parmastega aelidae, a newly described tetrapod from the earliest Famennian (Late Devonian) of Russia, provide detailed insights into the morphology and palaeobiology of the earliest tetrapods.
Journal ArticleDOI
Redescription of Holmia inusitata (Trilobita) from the Lower Cambrian of Scandinavia
TL;DR: Ahlberg et al. as mentioned in this paper used topotype data from the Lower Cambrian of Lauselva, southern Norway, for a redescription of Holmia inusitata.
Journal ArticleDOI
The dipnoan buccal pump reconstructed in 3D and implications for air breathing in Devonian lungfishes
TL;DR: 3D morphology of Rhinodipterus, a Mid-Late Devonian lungfish from Australia and Europe, based on synchrotron tomography and conventional microtomography scans suggests that it made more extensive use of air breathing than other Gogo or Bergisch Gladbach genera.
Journal ArticleDOI
Palaeoenvironmental signatures revealed from rare earth element (REE) compositions of vertebrate microremains of the Vesiku Bone Bed (Homerian, Wenlock), Saaremaa Island, Estonia

TL;DR: In this article, rare earth elements (REEs) have been analyzed from fossil vertebrate microremains (thelodont scales) from the Vesiku Bone Bed, Saaremaa, Estonia, using in situ microsampling by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS).
