mineralsArticleOnychites from Polish Jura and Their Functional MorphologyPrzemyslaw SztajnerInstitute of Marine and Environmental Sciences, University of Szczecin, 70-383 Szczecin, Poland; [email protected]: Onychites aff. barbatus is excessively rare within the Polish Jura. This paper describes a current uncover from the basal middle Oxfordian. The specimen is preserved within a manner common for other finds of this kind in platy limestones, i.e., as compressed and flattened imprints with remnants of Apricitabine web carbonized organic matter. Great preservation with the surfaces enables a precise reconstruction on the original structure. Accordingly, I hypothesize around the attachment to soft components as well as the function with the belemnite onychites. The high diversity of identified onychites, specially from Europe (NW Tethys), indicates that they served many different purposes. Keywords: onychites; mega-hooks; Belemnitida; functional morphology; Oxfordian; paleogeography1. Introduction Onychites have been first reported by Fraas [1], who described a single species that he named Onychoteuthis barbata. Quenstedt [2] described and illustrated 4BP-TQS supplier Further many species, such as O. barbata. Following subsequent minor revisions, one of the most total of that is that of Engeser [3], at present, ten types represented by quite a few specimens are recognized in the German Jura, ranging in the Pliensbachian to the reduced Tithonian. Further specimens were described from the Arctic (most lately [4]), from New Zealand [5], and, lately, from Poland [6]. Out of 27 specimens of belemnites with preserved arms like arm-hooks known from Europe (mostly Germany), only two bear onychites [5]. Hence, it truly is supposed that onychites had been a sexual feature, discovered in all probability in mature males who may have employed it for competition among one particular a further or for mating, analogous to many arm modifications inside the present-day cephalopods. Presumably, around the basis of th.
