Products description
On this piece, there is a rare trilobite of the species Anacheirurus adserai with excellently preserved antennae it comes along with a specimen of the species Bavarilla zemmourensis (Destombes et al., 1969). The species Anacheirurus adserai was originally described in 2007 as Lehua adserai. Therefore, this trilobite is still often identified under the genus Lehua, sometimes even still as Lehua vinculum (Barrande, 1872). Anacheirurus adserai is already a rare and sought-after trilobite species. However, finding one with well-preserved antennae is even rarer. Since the antennae are preserved on the negative side, the preparation focused on this side. Well actually it makes in this case little sense to distinguishing between positive and negative sides. On the plastic “positive side”, there are some non-loss-free adhesions from transferring from the cover plate. Restoration was nonetheless consistently avoided. The digestive tract is well-preserved, and the legs are partially visible. The antennae of Anacheirurus are excellently preserved. This piece comes completely without speculative carvings or colorations. As a second trilobite, the plate also features also a quite rare specimen of the species Bavarilla zemmourensis. This trilobite also shows traces of legs and antennae, but it is too close to the edge of the matrix, leaving insufficient space for the antennae. The legs could possibly be partially prepared. Nevertheless, the main attraction in this spectacular trilobite duo remains the Anacheirurus with its fine antennae. The piece comes with the positive and negative side. The Anacheirurus is about 25 mm long without antennae, and the Bavarilla measures approximately 22 mm in length. | |||
