Abstract:
In the studied paleontological site it can be observed a succession of green (V), grey (G1), red (R1), grey (G2), red (R2) and brown (M) stratigraphic levels of marly mudstones, separated by progressive boundaries. This succession becomes partially modified by a sandy channel structure (C) that interrupts the V, G1 and R1 levels by an erosive surface, and by a sulphated interval (S) that distorts, at least, the G2 level. The C structure and the G1, G2 and R2 (lower part) levels have an extremely rich and varied fossil accumulation.
The relative stratigraphical position and the paleontological content of "Lo Hueco" indicate that it could be attributed to the late Campanian-early Maastrichtian interval. The interpretation of its facies suggests a transitional brackish water to continental fresh water environment exposed to intermittent high to low energy intervals in the relatively arid and regressive global context of the Late Cretaceous.
