Abstract

Two agnostids from Cambrian of the Barrandian area bear different types of skeletal malformations. The tiny pathological exoskeleton of Hypagnostus parvifrons (Linnarsson, 1869) has asymmetrically developed pygidial axis, while the posterior pygidial rim in the larger Phalagnostus prantli Šnajdr, 1957 has an irregular outline.
