本研究旨在测试埋葬/暴露，沉积物类型，羽毛降解微生物的添加，以及添加矿物对羽毛保存的影响，并首次比较了这些国家在环境与升高的CO2大气中，以测试CO2对各种沉积环境下的降解和/或保存的影响。羽毛在化石记录中的特殊保存使我们对羽毛的发生和进化有了更好的理解。在这里，我们解决的因素，可能有助于保存羽毛在古代生物使用实验埋藏学。我们表明，大气中的中生代，已知是升高的二氧化碳和温度高于目前的水平，可能有助于保存这些软组织，促进羟基或碳酸羟基磷灰石的快速沉淀，从而超过自然降解过程。数据还支持微生物降解在二氧化碳浓度升高时得到增强，但矿物沉积也得到增强，通过稳定羽毛的有机成分有助于保存。
This study seeks to test the effect of burial/exposure, sediment type, the addition of feather-degrading microbes, and the addition of minerals on feather preservation, and for the first time, compares these states in ambient vs. elevated CO2 atmospheres to test the effect of CO2 on degradation and/or preservation under various depositional settings. The exceptional preservation of feathers in the fossil record has led to a better understanding of both phylogeny and evolution. Here we address factors that may have contributed to the preservation of feathers in ancient organisms using experimental taphonomy. We show that the atmospheres of the Mesozoic, known to be elevated in both CO2 and with temperatures above present levels, may have contributed to the preservation of these soft tissues by facilitating rapid precipitation of hydroxy- or carbonate hydroxyapatite, thus outpacing natural degradative processes. Data also support that that microbial degradation was enhanced in elevated CO2, but mineral deposition was also enhanced, contributing to preservation by stabilizing the organic components of feathers.
