A New Tristichopterid (Pisces, Sarcopterygii) from the Devonian of Latvia
Proceedings of the Latvian Academy of Sciences. Section B. Natural, Exact, and Applied Sciences., 2008 A New Tristichopterid (Pisces, Sarcopterygii) from the Devonian of Latvia A new species of tristichopterid sarcopterygians, Eusthenopteron kurshi, sp. nov., the earliest representative of the family reported to this date from the territory known as the Main Devonian Field, is described from the well-known fossil locality of Latvia, the Lode ...

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.Abstract Nearly half of all living vertebrate diversity can be traced back to a single lineage of lobe‐finned fishes (piscine sarcopterygians) that radiated during the Palaeozoic Era. In recent years, the phylogenetic framework of tetrapodomorph fishes has largely stabilized, with the exception of the ‘Osteolepiformes’, the interrelationships of which ...

Development of the Pectoral Lobed Fin in the Australian Lungfish Neoceratodus forsteri
Frontiers in Ecology and Evolution, 2021 The evolutionary transition from paired fins to limbs involved the establishment of a set of limb muscles as an evolutionary novelty. In parallel, there was a change in the topography of the spinal nerves innervating appendicular muscles, so that ...

Structural and functional divergence of growth hormone-releasing hormone receptors in early sarcopterygians: lungfish and Xenopus. [PDF]
PLoS ONE, 2013 The evolutionary trajectories of growth hormone-releasing hormone (GHRH) receptor remain enigmatic since the discovery of physiologically functional GHRH-GHRH receptor (GHRHR) in non-mammalian vertebrates in 2007.

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...

The giant cretaceous Coelacanth (Actinistia, Sarcopterygii) Megalocoelacanthus dobiei Schwimmer, Stewart & Williams, 1994, and its bearing on Latimerioidei interrelationships. [PDF]
PLoS ONE, 2012 We present a redescription of Megalocoelacanthus dobiei, a giant fossil coelacanth from Upper Cretaceous strata of North America. Megalocoelacanthus has been previously described on the basis of composite material that consisted of isolated elements ...

Uncovering a 500 million year old history and evidence of pseudogenization for TLR15
Frontiers in Immunology, 2022 IntroductionToll like receptors (TLRs) are at the front line of pathogen recognition and host immune response. Many TLR genes have been described to date with some being found across metazoans while others are restricted to specific lineages.
