AI-assisted summary
Description from the seller
Trilobite Gerastos granulosus – Enrollment — This specimen belongs to the species Gerastos granulosus, a trilobite of the family Phacopidae, that lived during the Middle Devonian (about 393–383 million years ago). It comes from the fossil formations of the Moroccan Anti-Atlas and is presented in an enrollment position, the defensive curling typical of trilobites, which allowed them to protect the more vulnerable parts of the body. Morphological characteristics: rounded and granulated cephalon: the surface of the glabella is covered with dense pustules and reliefs, a distinctive feature of the species (granulosus indeed means “granulated”). Schizochroal ( schizochroal ) eyes reduced, composed of small lenses, less prominent than those of other Phacopidae such as Drotops. Thorax short and compact, largely hidden by the curled position. Pygidium compact, completing the rounded shape of the specimen. Enrollment is not only an aesthetic trait, but represents a fundamental evolutionary adaptation: trilobites could close in on themselves, protecting the soft ventral side with the cephalic shield and the pygidium, just as armadillos or crustaceans do today. The genus Gerastos is well represented in the Devonian faunas of North Africa, where calcareous sedimentation conditions favored an extraordinary three-dimensional fossilization. Compared to other trilobites that are more slender or spiny, Gerastos granulosus stands out for its compact and robust forms, a morphology that probably reflects survival strategies based on passive defense. Main data: Species: Gerastos granulosus; Age: Middle Devonian (393–383 Ma); Class: Trilobita; Family: Phacopidae; Provenance: Anti-Atlas, Morocco; A fossil that combines scientific rigor and natural charm: the perfectly preserved enrollment, together with the granular texture of the cephalon, make this specimen of Gerastos granulosus a true small paleontological jewel, ideal for prestigious naturalistic collections.
Seller's Story
The Mineral Art Gallery offers minerals, fossils, shells and natural elements.
Born in Italy in 2017, today she collaborates with international galleries and collectors, she is a direct importer of large minerals and naturalistic collectible elements; deals with the processing to insert them inside the living space. A section of the gallery was dedicated to the Wunderkammer, "chamber of wonders or cabinet of curiosities" in which Mirabilia elements are presented: naturalia and italiania, a union between "the present is the past".
