Purujosa trilobite assemblage and the evolution of trilobite enrollment

Geology, 2011
Localities bearing abundant enrolled Cambrian trilobites are extremely rare, but here we report a new and exceptional such assemblage with a high diversity of enrolled specimens from the middle Cambrian of Spain. This novel find demonstrates that encapsulated enrollment was a behavioral response available to many of the early benthic trilobite morpho ...

Trilobite abnormalities

Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 1985
ABSTRACTThere is abundant evidence of injury, teratology and pathological conditions in trilobites although it is commonly difficult to distinguish between their morphological results. Many injuries were probably sustained during moulting, with spines, bilamellar fringes and narrow gaps between dorsal exoskeleton and doublure being most vulnerable ...
