- 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...
-
incomplete skeletons belonging to
three individuals. It is one of the
basalmost stegosaurs, as well as one of the
oldest known stegosaurs,
along with...
- it has one species, the type
species J. sinensis. This
species is the
basalmost ankylosaur known to have had a
proper tail club. In June 2008, farmer...

Kryptodrakon progenitor. The age of its
fossil remains made
Kryptodrakon the
basalmost and
oldest pterodactyloid known to date. In 2001,
pterosaur bones were...
- as stem-group caimans, but
Walter et al. (2022)
recovered them as the
basalmost alligatorines based on
phylogenetic analysis and
claimed that the earliest...

Ceratosuchops and
Riparovenator by
Barker et al.
recovered Camarillasaurus as the
basalmost member of the Spinosaurinae,
further supporting a non-ceratosaurian classification...
-
Protopteryx is an
extinct bird and
possibly the
basalmost enantiornithean, from the
Cretaceous period. The type
species is P. fengningensis. It was first...
- term "amphibians" can be ambiguous, however. In
modern phylogeny, the
basalmost tetrapods are
discerned from two
derived branches, one
consisting of the...
