Hydrodynamics of fossil fishes [PDF]
, 2014 Fromtheir earliest origins, fishes have developed a suite of adaptations for locomotion in water, which determine performance and ultimately fitness. Even without data from behaviour, soft tissue and extant relatives, it is possible to infer a wealth of ...

On the Maxillofacial Development of Mice, Mus musculus
Journal of Morphology, Volume 286, Issue 3, March 2025.This study focused on the craniofacial development of the mouse (Mus musculus), particularly the maxillofacial region. Using three‐dimensional reconstructions of histological sections combined with whole‐mount staining, we provided a detailed description of skeletal, neural, and vascular formation from the pharyngula (9.0 dpc) to late fetal stages (18 ...

Groenlandaspidid placoderm fishes from the Late Devonian of North America [PDF]
Records of the Australian Museum, 2003 Two new taxa of groenlandaspidid fish (Placodermi: Arthrodira) from non-marine deposits of the Catskill Formation (Upper Devonian) at Red Hill, Clinton County, Pennsylvania, USA, are the first to be described from North America outside of Greenland. Groenlandaspis pennsylvanica n.sp.

Precaudal Vertebrae in the Postcranial Region of Moray Eels Form Ventral Processes
Journal of Morphology, Volume 285, Issue 10, October 2024.The precaudal vertebrae in the postcranial region of moray eels form ventral processes with blood vessels. ABSTRACT Fish vertebrae are primarily morphologically classified into precaudal vertebrae jointed to the ribs and caudal vertebrae with hemal spines, through which the caudal artery and veins pass.

Discriminating signal from noise in the fossil record of early vertebrates reveals cryptic evolutionary history [PDF]
, 2014 The fossil record of early vertebrates has been influential in elucidating the evolutionary assembly of the gnathostome bodyplan. Understanding of the timing and tempo of vertebrate innovations remains, however, mired in a literal reading of the fossil ...

Première découverte d'un Arthrodire (Placodermi, Vertebrata) dans le Dévonien d'Amérique du Sud [PDF]
, 1996 Des plaques dermiques d'un grand Arthrodire eubrachyhtoracide (Placodermi, Vertebrata), provisoirement attribuées à un Dunkleosteidae, ont été découvertes dans les faciès détritique de la Formation de Colpacucho (Famennien), sur la Péninsule de Cumana ...

The braincase and jaws of a Devonian 'acanthodian' and modern gnathostome origins.
, 2009 Modern gnathostomes (jawed vertebrates) emerged in the early Palaeozoic era, but this event remains unclear owing to a scant early fossil record. The exclusively Palaeozoic acanthodians are possibly the earliest gnathostome group and exhibit a mosaic of ...

Darwin, Haeckel, and the “Mikluskan gas organ theory”
Developmental Dynamics, Volume 253, Issue 4, Page 370-389, April 2024.Abstract A previously unknown reference to the Russian ethnologist, biologist, and traveler Nikolai N. Miklucho‐Maclay (1846–1888) was discovered in correspondence between Charles Darwin (1809–1882) and Ernst Haeckel (1834–1919). This reference has remained unknown to science, even to Miklucho‐Maclay's biographers, probably because Darwin used the ...

PLoS ONE, 2017 Placoderms are considered as the first jawed vertebrates and constitute a paraphyletic group in the stem-gnathostome grade. The acanthothoracid placoderms are among the phylogenetically most basal and morphologically primitive gnathostomes, but their ...
