Holmidae trilobite examples Middle Cambrian; 500 million years ago to Permian Period; 252 million years ago Unknown excavation source From images, it is believed to be two exoskeletons of Holmidae trilobite, possible Andalusiana trilobites, but it is difficult to say as over 15,000 variants of the animal throughout 250 million years! This example may be from the middle and upper Ordovician period of North Africa and are the fossil continues to be sourced from Morocco. The word Trilobite means "three lobes" and each positive imprint specimen in this limestone matrix is a great representation of the animal's form. The matrix has been cut in an oval shape and removed from the surface to clearly showcase the Left & Right Pleural Lobes and the middle Axial Lobes of the animals. A stand could be fabricated to present the fossil upright for a beautiful natural and historic conversation piece in a home or office. Example measurements: 9.75" Height x 12.5" Width; 7.47 lbs.
