The Anticlinorium of Huayacocotla has several outcrops of geological and paleontological importance. However, reports of localities with paleoflora have been scarce so far. In this study, we report three new localities in the Cisuralian, the diversity and composition of which lead us to propose that the paleoflora may have been derived from vegetation that grew in an arid environment with seasonal wetness. The plant remains from the localities of Papaxtla and Calnali are highly transported and their diversity indicates the presence of several groups of plants that were shared with the La Virgen locality, which yielded the best preserved plant fossils. Changes in paleoenvironmental conditions indicate that the preservation of the flora was affected by the tectonic evolution of the region associated with sea level changes. The data presented here increase our knowledge of both the Cisuralian fossil flora and paleoenvironment in the south-central region of the Huayacocotla Anticlinorium, Hidalgo state.

Huayacocotla的Anticlinorium具有一些地质和古生物学重要性的露头。但是，到目前为止，有关古植物的报道很少。在这项研究中，我们报告了Cisuralian中的三个新地点，其多样性和组成使我们提出古植物可能源自于在具有季节性湿润的干旱环境中生长的植被。来自帕帕斯特拉（Papaxtla）和卡纳利（Carnali）地方的植物残骸被高度运输，其多样性表明与拉维根（La Virgen）地方共有几类植物，这些植物产生了保存最完好的植物化石。古环境条件的变化表明，植物区系的保存受到与海平面变化有关的区域构造演化的影响。
