- In phylogenetics,
basal is the

rooted phylogenetic tree or cladogram. The term may be more
strictly applied only to...

protostomes and the deuterostomes. It is
often suggested that the
basalmost bilaterians are the Xenacoelomorpha, with all
other bilaterians belonging...

Plesiosauria and
therefore it
represented by
definition the
basalmost known plesiosaur. This
analysis focused on
basal plesiosaurs and therefore...

Pachyrostra was coined,
uniting the two genera;
Achelousaurus is the
basalmost pachyrostran.
Shared derived traits (or synapomorphies) of the
group are...

Poekilopleuron as an afrovenatorine,
while Xuanhanosaurus was
recovered as the
basalmost metriacanthosaurid. However, the
position of
these taxa is very unstable...
