Abstract

An additional record of a coelurosaurian dinosaur in the uppermost Triassic of the Connecticut River Valley is provided by a block of sandstone bearing the natural casts of a pubis, tibia, and ribs. This specimen, collected nearly a century ago but hitherto unstudied, was brought to light by the junior author among the collections (at present in dead storage) of the Boston Society of Natural History. We are much indebted to Mr. Bradford Washburn and Mr. Chan W. Waldron, Jr., of the Boston Museum of Science for their assistance in making this material available for study.
