Abstract: PREMISE Cladoxylopsids, one of the first lineages with complex organization to rise from the plexus of structurally simple plants that comprised the earliest euphyllophyte floras, are moniliformopsid euphyllophytes. They formed Earth's earliest forests by the… read more here.

Abstract: PREMISE Cladoxylopsids formed Earth's earliest forests and gave rise to the ancestors of sphenopsids and ferns. Lower Devonian (Emsian) strata of the Battery Point Formation (Quebec, Canada) contain new anatomically preserved cladoxylopsids, one of which… read more here.

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.

DOI: 10.7717/peerj.12842
Abstract: Most previous publications on Devonian crinoids from the Holy Cross Mountains in Poland have concentrated on crinoid columns, and until now, little has been published about crinoid cups and calyxes. Herein, five crinoid taxa are… read more here.
