The discovery of dinosaur footprints in Jurassic strata from Meigu,Sichuan Province.

Geological Bulletin of China 36(6): 925-927 (in Chinese)



In August, 2016, three dinosaur footprints were discovered from the bottom of the Middle Jurassic Shaximiao Formation at the edge of the Xichang basin in Meigu, Sichuan Province.The dinosaur footprints are similar to Grallator.These footprints are significant for the study of geological climate, paleogeography and stratigraphic correlation.Further research should pay attention to the detailed classification of the dinosaur footprints.

First pterosaur footprints from the Tera Group (Tithonian–Berriasian) Cameros Basin, Spain.

The discovery of the Larañe (La Rioja, Spain) ichnological site provides the first outcrop pterosaur footprints in the Tera Group of the Cameros Basin. The footprint have characteristics similar to some of those already known in the Oncala Group, suggesting that possibly pterosaurs, which lived in this area during the deposition of the Tithonian–Berriasian sequences, were very similar. In this case, the footprints, assigned to Pteraichnus-like ichnogenus, are perfectly related to with those of morphotype A of the Los Tormos site (Soria) located in sediments of the Oncala Group.
