我们很高兴地得知，Retallack等人。（2023）同意我们关于Apis dorsata巢遗骸的结论，他们错误地将其识别为埃迪卡拉纪化石Dickonsonia tenuis（Meert等人，2023年，Retallack等人，2021，Retallack等人，2023年）。Retallack et al. 2023年，令人钦佩。埃迪卡拉化石的分类完全基于形态学，特别是当它们不能直接取样时，需要谨慎。Pandey等人最近提交的一份报告。（2023）为我们先前的结论提供了额外的支持，即所谓的化石是最近的起源。（2023）驳回了我们关于“化石”定位的论点，指出Dickinsonia化石有时可以弯曲，弯曲或横切层面（Gehling等人，2005年，Evans等人，2015; Runnegar，2022）。我们接受这一意见;然而，这些论点在这种情况下是没有实际意义的，因为"化石“位于一个最近的断裂面上，那里有一大块岩石从屋顶上分离出来。据我们所知，没有Dickinsonia化石形成沿着一个新生代倾斜断裂面的情况。Pandey等人（2023）后来证实了我们关于化石位置的观察。
We are delighted to learn that Retallack et al.(2023) agree with our conclusion regarding the remains of an Apis dorsata nest which they mistakenly identified as the Ediacaran fossil Dickonsonia tenuis (Meert et al., 2023, Retallack et al., 2021, Retallack et al., 2023). The mea culpa by Retallack et al.(2023) is admirable. The classification of Ediacaran fossils based exclusively on morphology, especially when they cannot be directly sampled, requires caution. A recent submission by Pandey et al.(2023) offers additional support for our earlier conclusion that the purported fossil is of recent origin.Retallack et al.(2023) dismissed our arguments about the positioning of the ‘fossil’noting that Dickinsonia fossils sometimes can curve, bend or cross-cut bedding planes (Gehling et al., 2005, Evans et al., 2015; Runnegar, 2022). We accept this observation; however, those arguments are moot in this case because the ‘fossil’is positioned on a recent fracture plane where a large piece of rock was detached from the roof. To the best of our knowledge, there is no case of Dickinsonia fossils forming along a Neozoic tilted fracture plane. Pandey et al.(2023) later confirmed our observations regarding the positioning of the fossil.
