Abstract

Vertebrate ichnotaxa described by George Frederic Matthew in 1910 from the Upper Carboniferous (Lower Pennsylvanian) ‘Fern Ledges’ of Saint John, New Brunswick, were dismissed as dubious trackways by previous authors. Thus, three new ichnospecies Matthew described appeared in the 1975 Treatise on Invertebrate Paleontology as “unrecognized or unrecognizable” and were mostly forgotten by vertebrate ichnologists. These traces include Hylopus (?) variabilis, Nanopus (?) vetustus and Bipezia bilobata . One ichnospecies, Hylopus (?) variabilis , here is retained as a valid tetrapod footprint ichnotaxon and reassigned to the ichnogenus Limnopus as a new combination, together with other poorly preserved specimens Matthew labeled, but never described. Nanopus (?) vetustus and Bipezia bilobata named by Matthew in the same paper, have been reexamined and remain as nomina dubia.
加拿大新不伦瑞克省圣约翰兰开斯特组上石炭世“蕨类岩壁”脊椎动物区系的重新评估
乔治·弗雷德里克·马修于1910年在新不伦瑞克省圣约翰的上石炭世(宾夕法尼亚下)“蕨类岩”中描述的脊椎动物ichnotaxa被先前的作者视为可疑的轨迹而不予考虑。因此,在1975年的《无脊椎动物古生物学专著》(Treatise on vertebrate Paleontology)中,马修所描述的三种新的鱼种被认为是“未被认识或无法识别的”,基本上被脊椎动物技术学家遗忘了。这些痕迹包括Hylopus (?) variabilis, Nanopus (?) vetustus和Bipezia bilobata。其中一个鱼种,Hylopus (?) variabilis,在这里被保留为一个有效的四足动物足迹鱼分类群,并作为一个新的组合被重新分配到Limnopus鱼属,与其他保存较差的标本一起,马修标记,但从未描述过。由Matthew在同一篇论文中命名的Nanopus (?) vetustus和Bipezia bilobata已被重新审查并保留为名义dubia。
