A comparison of crayfish burrow morphologies: Triassic and Holocene fossil, paleo‐ and neo‐ichnological evidence, and the identification of their burrowing signatures

摘要: The architectural and surficial morphologies of crayfish burrows from the Upper Triassic Chinle Formation Holocene sediments were compared in order to determine: 1) if could truly be attributed activity; 2) how comparable burrowing mechanisms are; 3) whether or not a common set signatures identified for both ancient modern freshwater crayfish. Materials used this study include members Formation, casts constructed by Procambarus clarkii Hobbs acutus (Girard) laboratory, naturally Cambarus diogenes di‐ogenes (Girard). burrow exhibit simple complex architectures, varying degrees branching, chamber, chimney development. They also relatively textured (bioglyphs) such as scrape scratch marks, mud‐ lag‐liners, knobby ...
