缠绕习性是一种攀缘策略，通过在其他植物周围使用回旋运动来帮助细长植物向上生长。在地质历史上，攀爬可能已经存在于第一个中泥盆世的森林中，正如可能的攀缘植物中的aneurophytaleanumnosperms [1]和石松[2]所示。到石炭纪晚期，攀缘植物变得更加普遍和多样化--它们保存在沼泽森林中，附着方式从气生根到叶子上的附属物，变成钩和卷须[3]。然而，所有这些攀援习性的诊断都是基于所声称的攀援植物的间接形态特征或与宿主植物的直接物理接触，但没有直接保存缠绕[3，4]。在石炭纪[5]中已保存了全矿化附生植物，但对据称是由潜在寄主植物的树干压缩上发现的缠绕物引起的疤痕的解释受到质疑[5]（见补充信息）。在中国东部的中新世山旺组中，只记录了一个真正缠绕在宿主周围的攀爬者的直接保存，尽管缠绕者的身份很难确定，很可能是一个自我缠绕者[6]。在这里，我们报告了一种攀缘蕨类植物，它在中国内蒙古早二叠世乌达凝灰岩化石Lagerstätte中围绕一种种子植物进行左手缠绕[7]。此外，根据其整体形态，宿主植物也可能是攀缘植物。这样一个攀爬者-攀爬者-攀爬者的现象标志着晚古生代森林潜在的生态复杂性。
The twining habit is a climbing strategy that helps slender plants grow upward by using circumnutation around other plants. In geological history, climbing may have already been present in the first Middle Devonian forests, as indicated by possible climbers among aneurophytalean progymnosperms [1] and lycopsids [2]. By the late Carboniferous, climbing was both more common and diverse — preserved in swamp forests with modes of attachment ranging from aerial roots to appendages modified into hooks and tendrils on the leaves [3]. However, all of these diagnoses of a climbing habit are based upon either indirect morphological characteristics of the purported climber or on direct physical contact with a host plant, but without direct preservation of twining [3,4]. Permineralized epiphytes have been preserved in the Carboniferous [5], but the interpretation of scars purported to have been caused by twiners that have been found on trunk compressions of potential host-plants has been questioned [5] (see Supplemental Information). Direct preservation of a climber engaged in true twining around a host has only been documented in the Miocene Shanwang Formation of Eastern China, albeit with the identity of the twiner difficult to establish and likely to be a self-twiner [6]. Here, we report a climbing fern engaged in left-handed twining around a seed plant from the early Permian Wuda Tuff fossil Lagerstätte of Inner Mongolia, China [7]. Moreover, the host plant is likely to also be a climber based on its overall form. Such a climber-climbing-a-climber phenomenon signals the potential ecological complexity of late Paleozoic forests.
