This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Pterygota

Characteristics

Palaeodictyopteroid insects share a unique mouthpart morphology. Their clypeus is much enlarged, and they have a distinctive beak formed by five elongate, stiff elements.

Discussion of Phylogenetic Relationships

Like most Paleozoic insects, paleodictyopteroids are known mostly from fossil wings. Due to a scarcity of suitable characters for phylogenetic analysis, the relationships between the subgroups have not been elucidated. Diaphanopterodea, Megasecoptera, and Permothemistida each show distinctive venational patterns and are therefore likely to be monophyletic groups; however, Paleodictyoptera is probably paraphyletic with respect to the other three subgroups (Grimaldi 2001).

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
