Products description
| This is a rather rare and interesting trilobite of the genus Bailiella from the upper Middle Cambrian of Morocco. Stratigraphically, is this presumably undescribed species is particularly interesting as it comes from the uppermost known part of the Moroccan Middle Cambrian. The so-called Bailiella Formation dates back to Destombes (1985), but a complete description is apparently still pending. The site is located south of Tinejdad, north of Alnif, and at the Jebel Ougnat Massif. This locality was only been collected at for a relatively short time and has not yielded many finds. The Bailiella Formation is widespread in the central Anti-Atlas but is usually poorly exposed. The lithology often forms steep slopes due to weathering, which are mostly buried by scree. Collecting and preparing the fossils is relatively laborious. Due to the high hardness and slight metamorphic overprint, the trilobites here are rarely found as split fossils, as is the case in the Wawrmast Formation. The hardness of the matrix makes preparation long and arduous. An interesting side effect is that fine crystals have grown on the trilobite. Nevertheless, the preservation quality is excellent, especially when compared to a typical Bailiella levyi from the Montagne Noire in France. The trilobite itself is about 75 mm long and represents an interesting and quite rare display piece. Destombes, J., Hollard, H. und Willefert, S. (1985). Lower Palaeozoic Rocks of Morocco. In: C.H.
