Thalassinoides和Ophiomorpha的分支洞穴系统在形态细节上差异很大。事实上，这两个属的个别洞穴成分可能在同一系统中同时出现，并可能进一步与螺旋洞穴Gyrolithes（本文重新描述）融合。然而，每个遗迹属内的主要形态特征往往是独特的，大多数标本可以相对容易地进行遗迹属鉴定。因此，尽管最近有人提出相反的建议，但这些遗迹属并不是严格意义上的同义词;在遗迹化石分类群中，这样的变异是可以预期的。此外，广泛的分类修订将破坏目前的稳定性和证明有用的现场应用和环境重建这些遗迹属概念。Spongeliomorpha遗迹属的定义是如此模糊，以至于这个名字应该被放弃，不管人们是否希望“分裂”或“合并”相关的洞穴遗迹属。
The branching burrow systems Thalassinoides and Ophiomorpha vary widely in morphological detail. Individual burrow components otherwise characteristic of these two genera may in fact occur together in the same system, and may further intergrade with the spiral burrow Gyrolithes (redescribed herein). Nevertheless, the predominant morphological traits within each ichnogenus tend to be distinctive, and most specimens can be identified ichnogenerically with relative ease. Thus, despite a recent suggestion to the contrary, these ichnogenera are not strict synonyms; such variations are to be expected among trace fossil taxa. Furthermore, extensive taxonomic revision would undermine the present stability and proven usefullness of these ichnogeneric concepts in field application and environmental reconstruction. The ichnogenus Spongeliomorpha is so ill-defined that the name should be abandoned, regardless of whether one wishes to "split" or " lump" the related burrow ichnogenera.
