Tipoolithus is an oogenus of fossil egg native to the Irbzer Formation in Morocco.

Its classification is uncertain, but it most closely resembles Laevisoolithids, and like members of that oofamily, it was laid by an enantiornithine bird or small theropod.

Tipoolithus is known from 12 small fragments of eggshell, so characteristics of the whole egg (like size and shape) are unknown.

[1] The eggshell of T. achloujensis seems to have dispersituberculate ornamentation, i.e., covered with randomly dispersed nodes, but some fragments show alignments or clusters of nodes, though none are complete enough to determine the full structure of its ornamentation.

It can certainly be classified into the Ornithoid-Ratite morphotype, and its similarity to Subtiliolithus suggests Laevisoolithid (Enantiornithes) affinities.
