ABSTRACT Vertebrate ichnology in North America has a long and distinguished history, starting with the remarkable discoveries by Edward Hitchcock of dinosaur footprints and trackways in the Connecticut River Valley. Hitchcock assembled a unique collection that is currently housed in the Beneski Museum of Natural History, Amherst College, and his work essentially constituted the beginnings of ichnology as a viable sub-discipline of paleontology. Although his original interpretation that these Late Triassic locomotion traces were bird tracks was incorrect, he indirectly linked birds and dinosaurs. Other talented amateurs including John Collins Warren, James Deane, Dexter Marsh and Roswell Field worked on these track sites and some were prolific authors.

技术在摄影史上的作用

摘要北美的脊椎动物学历史悠久而卓越，始于爱德华·希区柯克（Edward Hitchcock）在康涅狄格河谷发现的恐龙足迹和步道的非凡发现。希区柯克（Hitchcock）组装了一个独特的收藏品，目前收藏在阿默斯特学院（Amherst College）的贝内斯基自然历史博物馆中，他的工作从本质上构成了鱼类学的起点，成为古生物学可行的子学科。尽管他最初的解释是这些三叠纪晚期运动轨迹是鸟类轨迹，但是他间接地将鸟类和恐龙联系在一起。其他有才华的业余爱好者，包括约翰·柯林斯·沃伦，詹姆士·迪恩，德克斯特·马什和罗斯韦尔·菲尔德，都在这些赛道现场工作，其中一些人是多产的作家。博士有三本重要著作。
