Fig. 5. A in Dimerelloid brachiopod Dzieduszyckia from Famennian hydrocarbon seep deposits of Slaven Chert, Nevada, USA, with insights into systematics and paleoecology of the Dimerelloidea

Fig. 5. A. The distribution of the Roberts Mountains Allochthon with key mines cited in this study. B. Stratigraphy of the Roberts Mountains Allochthon. Note exact position of Dzieduszyckia within the Slaven Chert is unknown due to intense faulting within the allochthon. Base map modified from Holm-Denoma et al. (2017). Stratigraphic chart based on Ketner (2013).图5。A. 罗伯茨山推覆体（Roberts Mountains Allochthon）的分布情况与本研究涉及的关键矿区。B. 罗伯茨山推覆体的地层序列。需注意，受该推覆体内部强烈断层作用影响，Dzieduszyckia在斯莱文燧石（Slaven Chert）中的精确产出位置尚未明确。本图底图改编自Holm-Denoma等（2017）的研究；地层柱状图参考自Ketner（2013）的成果。
