5" Parahomalonotus calvus Trilobite - Foum Zguid, Morocco

This is a species not normally seen from the Timrhanrhart Formation, Parahomalonotus calvus. It's 5" long, and would have been significantly longer, but it's been heavily compressed lengthwise. Nearly all of the specimens from this layer show heavy compression or distortion based on their orientation.

Please Note: I believe the front half and back half of this trilobite maybe a composite of two partial specimens. There is a suspicious crack around the forth segment, and the segment count appears to be 12 not 13, but it also looks like there might be a segment pushed under the head. Otherwise there is only some minimal shell restoration on the left hand side. Due to the possible composited nature of this trilobite, the price is significantly discount.

About Trilobites

Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
