The pelvic fin and girdle of Panderichthys and the origin of tetrapod locomotion
One of the most marked transformations in the vertebrate transition to land was that of fins to limbs. This transformation involved not only the generation of morphological novelties (digits, sacrum)Expand

Fish fingers: digit homologues in sarcopterygian fish fins.
A defining feature of tetrapod evolutionary origins is the transition from fish fins to tetrapod limbs. A major change during this transition is the appearance of the autopod (hands, feet), whichExpand

Comparative pelvic development of the axolotl (Ambystoma mexicanum) and the Australian lungfish (Neoceratodus forsteri): conservation and innovation across the fish-tetrapod transition
BackgroundThe fish-tetrapod transition was one of the major events in vertebrate evolution and was enabled by many morphological changes. Although the transformation of paired fish fins into tetrapodExpand

The humerus of Panderichthys in three dimensions and its significance in the context of the fish–tetrapod transition
The humerus of Panderichthyshas been considered to represent a transitionalform between that of tetrapodomorph fish such asEusthenopteronandtetrapods such asAcanthostega. The previous description wExpand

The pectoral fin of Panderichthys and the origin of digits
One of the identifying characteristics of tetrapods (limbed vertebrates) is the presence of fingers and toes. Whereas the proximal part of the tetrapod limb skeleton can easily be homologized withExpand

Development and Evolution of the Muscles of the Pelvic Fin
Locomotor strategies in terrestrial tetrapods have evolved from the utilisation of sinusoidal contractions of axial musculature, evident in ancestral fish species, to the reliance on powerful andExpand

The Ancient Origins of Neural Substrates for Land Walking
Walking is the predominant locomotor behavior expressed by land-dwelling vertebrates, but it is unknown when the neural circuits that are essential for limb control first appeared. Certain fishExpand

Assessment of the Antioxidant and Antibacterial Activities of Three Species of Edible Seaweeds
Extraction of secondary metabolites from St. Lawrence Estuary edible seaweeds – Saccharina longicruris, Ascophyllum nodosum and Ulva lactuca – was carried out by pressurized liquid extraction usingExpand

Fossil Musculature of the Most Primitive Jawed Vertebrates
From Jawless to Jawed The earliest vertebrates were jawless. Past reconstructions have assumed that the primitive jawed condition was much like that found in sharks. Trinajstic et al. (p. 160,Expand
