limits of life revealed in a silicified micro-ecosystem: Sphenophyllum stems, and roots trapped inside an arthropod boring in a Permian calamitalean. Palaeontographica Abteilung Abstract One of the youngest known occurrences of anatomically preserved Sphenophyllum Brongniart 1828 is reported from the Permian Motuca Formation, Parnaíba Basin, central-north Brazil. At least 31 stems, densely interwoven to each other and associated with tiny roots and leaves of this extinct herbaceous sphenopsid, were found in a silica-petrified state. Originally grown upright, they squeezed into in the pith of the arborescent calamite Arthropitys barthelii N EREGATO et al. 2017, which was additionally caved by putative xylophagous herbivores. Although restricted within natural limits, the Sphenophyllum organs show different developmental stages that encompass a majority of juvenile stems and a few ones with initial secondary growth. The stems are of circular to elliptical outline and consist of a central triarch actinostele made of primary vascular tissues and a variable amount of wood. Extraxylary tissues comprise a narrow innermost zone with putative phloem, internal periderm made of
硅化微生态系统揭示的生命极限:二叠纪灾难动物节肢动物洞穴中被困的蝶叶茎和根。摘要在巴西中北部Parnaíba盆地的二叠纪Motuca组中发现了解剖学上保存最年轻的Sphenophyllum Brongniart 1828。至少有31根茎，彼此紧密地交织在一起，并与这种已灭绝的草本蝶科植物的微小根和叶子联系在一起，被发现处于硅石化状态。它们原本是直立生长的，后来被挤进了乔木菖蒲(Arthropitys barthelii) (EREGATO et al. 2017)的髓内，这颗菖蒲还被假定的食木食草动物穴居。虽然受自然限制，但叶柄各器官的发育阶段不同，大部分幼茎和少数幼茎具有初级次生生长。茎呈圆形至椭圆形，由一个由初级维管组织和可变数量的木材组成的中央三拱形放线骨组成。叶鞘外组织包括一个狭窄的最内层带假定韧皮部，内周由
