DOI: 10.1002/ajb2.16082
Abstract: PREMISE Trimerophytes are a plexus of early tracheophytes that form the base of the euphyllophyte clade and, thus, represent the link between the earliest land plants and modern-day ferns, sphenophytes, and seed plants. As the… read more here.

DOI: 10.1016/j.lithos.2020.105393
Abstract: Abstract Late Silurian-Early Devonian granites are widespread in the Miramichi Highlands of New Brunswick, but their petrogenesis is controversial and hinders an understanding of the geological evolution of the Canadian Appalachians. Here we present a… read more here.

Braincase and endocast anatomy in porolepiforms (Sarcopterygii: Dipnomorpha): evidence from the Early Devonian (Emsian) ‘porolepidid’ Durialepis edentatus
Sign Up to like & getrecommendations! Published in 2024 at "Earth and Environmental Science Transactions of the Royal Society of Edinburgh"
DOI: 10.1017/s1755691024000057
Abstract: ABSTRACT Porolepiforms represent one of the key lineages of early lobe-finned fishes. They include two taxonomic groupings: the paraphyletic ‘porolepidids’, characterised by rhombic scales and extensive development of cosmine on dermal bones; and the monophyletic,… read more here.
