A new ichnospecies, Glossifungites gingrasi n. isp., is described from multiple locations in basal sand-filled coastal plain distributary channels of the Turonian (Upper Cretaceous) Ferron Sandstone (central Utah). Glossifungites gingrasi n. isp. is attributed to the ichnogenus Glossifungites based on the presence of scratch imprints, passive fill, and a tongue-shaped structure, yet the new ichnospecies is distinct because it displays transverse bioglyphs that run perpendicular to the planiform structure, which contrasts to the axis parallel bioglyphs present in the ichnospecies G. saxicava. The transverse arrangement of ornamentation exhibited by G. gingrasi n. isp. is observed in modern subaqueous insect burrows produced by mayfly and chironomid larvae, and constitutes a way to differentiate insect-generated burrows from structures produced by crustaceans that are known to create other Glossifungites ichnospecies. Differentiating insect- from crustacean-generated burrows is significant because it provides a way to distinguish bioturbation by marine-recruited fauna from that produced by freshwater fauna in the rock record, making G. gingrasi n. isp. a valuable ichnological tool for paleoenvironmental and stratigraphic interpretation. While G. gingrasi n. isp. may represent a burrow created by a variety of filter-feeding subaqueous insects, the large size of G. gingrasi n. isp. in the Ferron Sandstone suggests that the largest specimens are probable mayfly burrows and supports the assertion that burrowing mayflies (e.g., Polymitarcyidae and Ephemeridae) adapted to domicile filter-feeding during or prior to the Turonian.UUID: http://zoobank.org/a033b22f-bf09-481a-975e-3a1b096154cc

Glossifungites gingrasi n. isp.，可能是来自犹他州白垩纪 Ferron 砂岩的水下昆虫栖息地

一个新的物种，银杏n. isp.，在图伦（上白垩统）铁龙砂岩（犹他州中部）的基底充砂沿海平原分流河道的多个位置进行了描述。银杏n. ISP。归因于 ichnogenus光泽菌基于划痕、被动填充和舌形结构的存在，但新的鱼种是不同的，因为它显示垂直于平面结构的横向传记，这与鱼种中存在的轴平行传记形成对比G.萨西卡瓦. 纹饰的横向排列G.金格拉西n. ISP。在由蜉蝣和摇蚊幼虫产生的现代水下昆虫洞穴中观察到，并且构成了一种区分昆虫产生的洞穴与甲壳类动物产生的结构的方法，这些结构已知会产生其他光泽菌物种。区分昆虫和甲壳类动物产生的洞穴很重要，因为它提供了一种方法来区分海洋招募动物群的生物扰动与岩石记录中淡水动物群产生的生物扰动，使得G.金格拉西n. ISP。用于古环境和地层解释的宝贵技术工具。尽管G.金格拉西n. ISP。可能代表由多种滤食性水下昆虫形成的洞穴，G.金格拉西n. ISP。Ferron 砂岩中的研究表明，最大的标本可能是蜉蝣洞穴，并支持挖洞蜉蝣（例如，Polymitarcyidae 和 Ephemeridae）在 Turonian.UUID 期间或之前适应栖息滤食的断言：http://zoobank.org/a033b22f-bf09-481a-975e-3a1b096154cc
