Hollardops Mesacristata Trilobite from Morocco (285.8 grams)
Trilobites, an early arthropod relative of spiders, horseshoe crabs, and scorpions, preserved in this level of detail only occurred as a result of very sudden underwater landslides called turbidite sequences, which ravaged the early earth when the continents were still very much on the move. The contorted body positions of the trilobites demonstrate a final fight against being buried alive. Notice the many eye facets present on this example. The Asteropyginae recently have undergone revision. This one has been known in the past as Metacanthina, an entirely different trilobite.
This one has many fine details present, including pustules on the genals. This one has been prepared in a reflexed position, making a striking display. Size of Trilobite: 2.75 Inches. Location: Emsian, Middle Devonian, Taharajat, Djebel Oufaten, Atlas Mountains, Morocco. Size: 3 x 1.5 x 3 inches.
Size of Trilobite: 2.5 Inches.
