Description
Museum quality Walliserops trifurcatus Trilobite for sale. Walliserops is a genus of Trilobite known mainly from Jbel Gara near Foum Zguid. Three described species occur here: Walliserops trifurcatus, Walliserops hammii, Walliserops tridens. Three new proposed undescribed species known from other locations in Morocco (Jbel Issoumour). The genus Walliserops is closely related to the genus Comura.
The purpose of the outstanding horns is not clear, although they must be important to show off like that. Some think they are used to direct food to the mouth. Some believed it is sexual dimorphism until other species with different forks where found. Would it be a fighting weapon, like beatles antlers? Are they sensors? Are they there to make them look bigger?
The fossil is 7.6 cm or 3 inches with the forked front extension measured. The bend is hard to measure, it is maybe bigger. The initial crack runs through the tips of the tail spines and another through the fork. Don’t see any others.
These cracks are not avoidable. They occur, when quarry workers crack the rock in order to find fossils. Fossils don’t grow on rocks, they hide inside. Unfortunately in the layers of the hardy Devonian rocks fossils appear in all directions. Once the rock is broken the fossil is discovered. Due to the nature of these rocks and the position of the fossil, the fossil is broken too. Experienced Preparators take on the task to glue them back together and to chisel or grind them out. In general cracks and some preparation marks are not avoidable and show that the fossil is real and not faked. There is no damage or replaced parts on this Trilobite.
The availability of pneumatic and air abrasive tools makes the work of the preparator even more efficient and qualitative upgraded. Features of the eyes, the body markings (pores etc.) and spines can be easier prepared out of the hardy rocks. Chemicals like Rewoquat can be also helpful in the preparation process.
Moroccan Trilobites like this Walliserops trifurcatus Trilobite for sale from Morocco are often master pieces of preparation art. Mining of fossil and their preparation is a great source of income for the people, that live in the oasis of the Sahara desert. Whole villages depend on it.
I examine all fossils carefully. I am aware that there is fakes out there and I have some, which I will not sell. If you have any question regarding the fossil, feel free to contact me. The fossils sold here are all authentic as stated also in terms and conditions. Alternations from the preparation process will be pointed out. The same rules for cracks. I will tell you about existing cracks. Also because I don’t consider good repaired cracks as damage.
This Walliserops trifurcatus Trilobite for sale is an authentic fossil. The fossil measures 9 cm or 3.5″ from the front tip of the fork to the end of the tail.
