Aves are relatively rare as fossils in cave environments in Brazil, particularly in the Northeast region, where, until now, only one individual has been registered in a cave in Bahia. Here we focus on the taxon identification, ichnology, and biostratinomic analysis of avian remains discovered at Toca da Boa Vista cave, Campo Formoso, Bahia, Brazil. Taxonomic and anatomical identification of the elements was conducted and compared with those of individuals housed in museum zoological collections. The marks on the elements were observed following ichnotaxonomic guidelines and compared with descriptions of ichnotaxa on bone substrates, while macroscopic biostratinomic characteristics were individually analyzed. The elements were identified as belonging to . Notably, perforations on ulna and tibiotarsus were attributed to the ichnospecies s, likely made by a felid. Although the cause of death remains undetermined, the evidence suggests that the individual probably died inside the cave. Decay characteristics point to low scavenger activity, and the presence of all groups of transportation, the absence of abrasion, a low stage of weathering, and the knowledge ethological and ecological about further support this hypothesis.

巴西东北部首次发现火鸡秃鹫 (Cathartes aura) 化石记录：分类学、考古学和埋藏史

在巴西的洞穴环境中，鸟类化石相对罕见，特别是在东北地区，到目前为止，在巴伊亚的洞穴中只记录到了一只鸟。在这里，我们重点关注在巴西巴伊亚州坎波福尔莫索的托卡达博阿维斯塔洞穴中发现的鸟类遗骸的分类单元鉴定、地层学和生物地层学分析。对这些元素进行了分类学和解剖学鉴定，并与博物馆动物收藏中的个体进行了比较。按照鱼类分类学指南观察元素上的标记，并与骨基质上鱼类分类的描述进行比较，同时单独分析宏观生物层学特征。这些元素被确定为属于 。值得注意的是，尺骨和胫跗骨上的穿孔归因于物种，很可能是由猫科动物造成的。尽管死因尚未确定，但有证据表明该人可能死在洞穴内。腐烂特征表明清除剂活动较低，所有运输群体的存在，没有磨损，风化阶段较低，以及有关动物行为学和生态学的知识进一步支持了这一假设。
