Cranidium NM-L 15148 selected by Šnajdr (1984: 169), figured by Hawle and Corda (1847: pl. 1, fig. 5) as Acanthopyge Leuchtenbergii. Refigured by Barrande (1852: pl. 28, figs 40, 41), Šnajdr (1984: pl. 5, fig. 13) and discussed by Thomas and Holloway (1988: 221–222).</p> <p>Ty p e l o c a l i t y.

Two hypostomes enables positive determination as belonging to the juvenile (early holaspid) specimens of Acanthopyge (Acanthopyge) haueri (BARRANDE, 1846), which is a common, eponymous species of Acanthopyge Limestone facies. Both hypostomes show all features typical for juvenile specimens of this species – especially coarse, prominent granulation of the middle body and prominent terrace lines on lateral and posterior margin.</p> <p>One fragment of cranidium (Text-fig. 3l) possibly also belongs to this species. Only a median glabellar lobe covered by coarse tubercles and spinose tubercles is observable, with a very narrow fragment of supposed bullar lobe. It could not be entirely excluded, however, that this fragment may be a remnant of odontopleurid Ceratocephala WARDER, 1838 – the median lobe does not widen anteriorly, but such a feature is also present in some specimens of Acanthopyge (Acanthopyge).</p> </div>	https://treatment.plazi.org/id/912E6907FFBAFFF8FCFE8138C694F7E2	Public Domain	No known copyright restrictions apply.

Eight incomplete cephala, six pygidia, numerous isolated fragments of cephala, pygidia and thoracic segments, two incomplete cheeks with preserved visual surface of the eye. Internal moulds and their counterparts, twenty five total remnants.</p> <p>R e m a r k s. Preservation of even the best-preserved remains of phacopid exoskeletons does not allow positive determination of material to the species level, but it shares most features with Chotecops hoseri (HAWLE et CORDA, 1847). The angle of divergence in axial furrows is, however, slightly larger in the studied material (67°), but this value is barely larger than the upper limit of the variation range (60–65°) previously known in this species (Chlupáč 1977: 53); this feature may have also been slightly affected by deformation. In the studied samples, the maximal number of lenses in the dorso-ventral row of the eye reaches 6 (5) ommatidia (in two young holaspid specimens, see Text-fig. 3d and younger unfigured specimen CGS MM 575), which fits well with description of Chotecops hoseri by Chlupáč (1977: 53). A lesser maximal number of ommatidia in a dorso-ventral row in the younger specimen can be explained by its early ontogenetic stage. In the largest specimen, the number of dorso-ventral rows in an eye is 17, and some are clearly missing (broken off). Following Chlupáč (1977), specimens of Chotecops hoseri should reach 18 dorsoventral rows. Pygidia correspond with C. hoseri in number of ribs (4–5, 6 in large specimens only; see Chlupáč 1977)), by their PL/PW ratios, and by prominent effacement of pleural furrows, except for the first one (two) pairs. The exact number of axial rings in studied specimens remains unknown because of poor preservation, but certainly exceeds four well-expressed rings. The studied remains differ from Chotecops auspex CHLUPÁČ, 1971, also rarely occurring in the Acanthopyge Limestone (Chlupáč 1971, 1977, 1983), in having slightly larger eyes with more dorsoventral files of ommatidia, and by better expressed pygidial segmentation (much effaced in C. auspex). However, the observed angle of divergence in cephalic axial furrows fits better to the latter-mentioned species.</p> </div>	https://treatment.plazi.org/id/912E6907FFBAFFF8FF688456C4F0F962	Public Domain	No known copyright restrictions apply.

Among trilobite remains from the locality, apart from ubiquitous phacopids and very fragmentary but common harpetids, remains of scutelluid trilobites are distinctive. They do not enable determination at the species level, and barely at the generic level.Despite this, it is apparent that they do not represent remains of Thysanopeltis HAWLE et CORDA, 1847, or Scabriscutellum RICHTER et RICHTER, 1956 (the only scutelluid genera mentioned in Acanthopyge Limestone by Chlupáč 1983; see also discussion below). Pygidial fragments are characterised by wide, only moderately vaulted paired ribs, middle rib possessing coarse granulation (large granules, pustules), and very narrow inter-rib furrows. The axis is not preserved, with the exception of a narrow fragment figured in Text-fig. 4e; also, the pygidial outline is barely determinable, possibly semielliptical. Because of insufficient preservation, affiliation of all these samples to the Scutellum sensu lato seems to be the most parsimonious solution. Occurrence of Scutellum PUSCH, 1833 and allied taxa (for example, Torleyiscutellum BASSE, KOCH et LEMKE, 2016, Goldius DE KONINCK, 1841; see also Weiner et al. 2018) is characteristic for the Middle and Upper Devonian of Laurussia (current France, Germany, Belgium or Poland), see, for example, Archinal (1994), Van Viersen and Prescher (2011) and Basse et al. (2016).</p> </div>	https://treatment.plazi.org/id/912E6907FFBCFFFEFEC18417C7CBFB09	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

One isolated pygidium apparently belongs to the subfamily Proetinae – it is prominently vaulted, with a semi-elliptical outline, wide, robust axis and well developed, moderately vaulted posterior margin with shallow, wide border furrow. However, its generic affiliation is uncertain. The above-discussed features, together with well-developed axial rings and deep pleural furrows on lateral pygidial lobes preclude its determination as Orbitoproetus, commonly occurring in Acanthopyge Limestone in the Kobyla area. An affiliation to Longiproetus ? sp. seems to be most suitable (note also a similar number of axial rings – at least 7, plus short terminal part, for Longiproetus 8(7) axial rings is a diagnostic feature). From Erbenites PŘIBYL, 1964, typical for this part of Acanthopyge Limestone, a different number of axial rings (only 4, plus long terminal part in Erbenites), wider and deeper pleural furrows and different vaulting of pygidium with much deeper and wider border furrow clearly distinguish the described pygidium. From Coniproetus (Tropiconiproetus) ŠNAJDR, 1980, the discussed pygidium differs especially by much deeper and wider pleural furrows. With some uncertainty, an incomplete isolated free cheek figured in Text-fig. 4c is also affiliated to Longiproetus.</p> </div>	https://treatment.plazi.org/id/912E6907FFBCFFFCFB88837BC7B5FC75	Public Domain	No known copyright restrictions apply.

It is barely determinable, because all details are effaced by re-crystallization. Only preliminary affiliation to the Eremiproetus is possible, based on overall (slightly violinshaped) outline of glabella and, especially, the course of the preocular facial suture, diverging slightly anteriorly. The medium-vaulted frontal border is less arched and narrower than in E. eremita (BARRANDE, 1852). An indistinct median tubercle is present on the anterior part of the occipital lobe. On much of the fragmentary internal mould, indistinct coarse granulation on the surface of the glabella is present. Fragment of the cranidium, possibly because of its heavy corrosion, is somewhat reminiscent of the invalid species E. hornyi PŘIBYL, 1965 (established on corroded specimen, encompassed by Šnajdr (1977, 1980) into the synonymy of E. eremita), and by some features, especially by narrower and less vaulted anterior border and glabellar granulation, also reminiscent of E. notabilis (G. ALBERTI, 1966) sensu Feist and Belka (2018: text-fig. 3R, S). Due to some of abovediscussed characters, the cranidium is also reminiscent of cornuproetid Tafilaltaspis G. ALBERTI, 1966 which, however, has not yet been described from the Acanthopyge Limestone, but is known from underlying Suchomasty Limestone facies, upper Emsian in age. From Nagaproetus ŠNAJDR, 1977, a fragment of the cranidium differs by a diverging preocular branch of the facial suture, and from Proetopeltis PŘIBYL, 1965 and Buchiproetus PILLET, 1969, by the outline of the cranidium and the shape of the frontal border.</p> </div>	https://treatment.plazi.org/id/912E6907FFBEFFFCFEF480EBC048FC8C	Public Domain	No known copyright restrictions apply.

One incomplete exfoliated cranidium.</p> <p>R e m a r k s. Only one poorly preserved cranidium with corroded glabella does not enable safe affiliation within the tribe Otarionini RICHTER et RICHTER, 1926, but its general morphology corresponds well with the overall body morphology of Otarion lacrimarum PŘIBYL et VANĚK, 1981, previously described from the Acanthopyge Limestone. The specimen has been compared with the type material of this species, which is housed in collections of the Czech Geological Survey (prefix CGS), not in the Museum of Senckenberg Institute (prefix SMP) as has been published (unfortunately with low quality of photographs) in Přibyl and Vaněk (1981). The glabella of the studied specimen is relatively elongated, widening slightly anteriorly, mediumvaulted, covered by sparse distinct granules. It differs from the Cyphaspis BURMEISTER, 1843 in having a relatively longer preglabellar field, and markedly lesser convexity of the glabella (Van Viersen and Prescher 2007, Van Viersen and Holland 2016). This convexity of glabella is, on the other hand, more prominent than in Harpidella MCCOY, 1849 (sensu Adrain and Chatterton 1995). By some features (sparse granulation, sag. length of occipital ring+glabella/ sag. length of cranidium ratio; see Adrain and Chatterton 1995: 308), the studied cranidium is similar to the abovediscussed genus. L1 are not preserved (they are broken off, but the remains of left L1 indicate its large sag. length). Affiliation of the specimen as Otarion cf. lacrimarum seems to be the most likely, although typical elevation at the sag. axis of the preglabellar field (cf. Přibyl and Vaněk 1981: 194) is indistinct in the studied specimen, probably due its corrosion.</p> </div>	https://treatment.plazi.org/id/912E6907FFBEFFFDFC25836AC58DFC0D	Public Domain	No known copyright restrictions apply.

Three fragments of free cheeks.</p> <p>R e m a r k s. Two remnants of free cheeks are strongly vaulted; eyes are broken off. Lateral border furrow is wide, deep, lateral border strongly vaulted, narrow in one specimen but these features are almost indistinct in second specimen (its morphology is effaced). The third, most doubtful fragment may be a remnant of a tropidocoryphid free cheek with a long spine. All these remains are too much fragmentary to enable any more precise affiliation.</p> </div>	https://treatment.plazi.org/id/912E6907FFBEFFFCFB9F86A3C013FB08	Public Domain	No known copyright restrictions apply.
