- In phylogenetics,
basal is the
direction of the base (or root) of a
rooted phylogenetic tree or cladogram. The term may be more
strictly applied only to...
- the
protostomes and the deuterostomes. It is
often suggested that the
basalmost bilaterians are the Xenacoelomorpha, with all
other bilaterians belonging...
- the most
southern distribution. The
genus Aptenodytes appears to be the
basalmost divergence among living penguins. They have
bright yellow-orange neck...
- Its
remains were
discovered in the
Posongchong Formation. It is the
basalmost known tetrapodomorph. Lu, J.; Zhu, M.; Long, J. A.; Zhao, W.; Senden,...

generally find more
recent (Late
Carboniferous to Permian) age for the
basalmost divergence among lissamphibians. The

incomplete skeletons belonging to
three individuals. It is one of the
basalmost stegosaurs, as well as one of the
oldest known stegosaurs,

-
Kryptodrakon progenitor. The age of its
fossil remains made
Kryptodrakon the
basalmost and
oldest pterodactyloid known to date. In 2001,
pterosaur bones were...

Walter et al. (2022)
recovered them as the
basalmost alligatorines based on
phylogenetic analysis and
claimed that the earliest...

species J. sinensis. This
species is the
basalmost ankylosaur known to have had a

- term "amphibians" can be ambiguous, however. In
modern phylogeny, the
basalmost tetrapods are
discerned from two
derived branches, one
