Collection methods and comments
Reason for describing collection: | taxonomic analysis |
Collection method comments: The specimen was collected by a local farmer. One of the authors (JL) later visited the fossil locality, guided by the farmer. Because the specimen was not excavated by a technically accomplished collector, it was heavily damaged during excavation. During the visit to the site, JL and the collector found a fragment of black bone from a pterosaur, which is identical to the present specimen in color. Thus, we are confident that the locality the farmer pinpointed is the locality where the specimen described here was collected. The specimen comes from gray-green tuffaceous shales (Fig. 2), which based on lithology are most likely belonging to the second member of the Upper Jurassic Tuchengzi Formation (Bureau of Geology and Mineral Resources of Liaoning Province, 1989).
