Abstract
The fossil record of pterosaurs in northwestern Gondwana has been relatively scarce, with only two previous occurrences. This study presents new pterosaur findings from three sites in Colombia, including a new record of an Anhanguera-like specimen and other bones referrable to Anhangueria. The new material includes a distinctive partial lower jaw found in association with parts of a radius and a complete distal syncarpal. The lower jaw has a triangular glenoid fossa in dorsal view, a fossa depressoria with a bean-shaped outline, and a retroarticular process with a straight margin in lateral or medial views. The new fossils extend the record of Anhanguera-like pterosaurs into the earliest part of the Cretaceous and expand our knowledge of the vertebrate fossil record of lower latitudes.
期刊介绍:
Papers must have a regional appeal and should present work of more than local significance. Research papers dealing with the regional geology of South American cratons and mobile belts, within the following research fields:
-Economic geology, metallogenesis and hydrocarbon genesis and reservoirs.
-Geophysics, geochemistry, volcanology, igneous and metamorphic petrology.
-Tectonics, neo- and seismotectonics and geodynamic modeling.
-Geomorphology, geological hazards, environmental geology, climate change in America and Antarctica, and soil research.
-Stratigraphy, sedimentology, structure and basin evolution.
-Paleontology, paleoecology, paleoclimatology and Quaternary geology.
New developments in already established regional projects and new initiatives dealing with the geology of the continent will be summarized and presented on a regular basis. Short notes, discussions, book reviews and conference and workshop reports will also be included when relevant.
