The term " Batrachomorpha " is however sometimes used in an cladistic sense to denote Labyrinthodonts more closely related to modern amphibians than to amniotes.
22.
Several authors have suggested that terrestrial eggs evolved from amphibian eggs laid on land to avoid predation on the eggs and competition from other labyrinthodonts.
23.
Branchiosaurs were small-bodied and had simple conical teeth, while labyrinthodonts were larger and had complex, folded dentin and enamel in their teeth.
24.
With the reinterpretation of the Ichthyostegalia as aquatic forms, baphetids are good candidates for the spot of first labyrinthodont group to actually spend substantial time on land.
25.
Exactly what labyrinthodonts are in the stem group tetrapods rather than the corresponding crown group is uncertain, as the phylogeny of early tetrapods is not well understood.
26.
The finds by Hislop and Hunter included a new species of Labyrinthodont reptile, " Brachyops laticeps " that was described by Richard Owen in 1854.
27.
Relative to other early tetrapods ( labyrinthodonts ), they had simplified backbones, where the whole vertebra was made of a single intercentrum, topped by a neural arch.
28.
The increasing knowledge of Labyrinthodonts from Romer's gap has led to the challenging of the hypothesis that pentadactyly, as displayed by most modern tetrapods, is plesiomorphic.
29.
While most labyrinthodonts remained aquatic or semi-aquatic, some of the reptile-like amphibians adapted to explore the terrestrial ecological niches as small or medium-sized predators.
30.
"Mastodonsaurus " and other similar animals were referred to as labyrinthodonts, named like " Labyrinthodon " for teeth that were highly folded in cross section.
