holaspis

Definitions

A stage in the development of a trilobite at which the creature has gained its adult segmentation, but continues to molt and grow.

Examples

“A similar situation may also characterize S. wenlockiana, a species with six segments in holaspis, the smallest holaspids of which have⟳ similar glabellar lengths to those of the sixth degree meraspis of A. konincki.”

“The pygidial spines are stout and direct⟳ outward in the early holaspis (Fig. 2, A-B, F), but become⟳ slender and direct⟳ inward in the late holaspis (Fig. 2, D, E).”

“The holaspis stage⟳ has a full complement of thoracic segments for the species but growth continues through further molts and maturity may not be reached until some time after the holaspis stage⟳ was reached.”
