Yacoraite Formation
Template:Short description Script error: No such module "Infobox".Script error: No such module "check for unknown parameters".
The Yacoraite Formation is a largely Mesozoic geologic formation. The deposits of this formation mainly date from the Maastrichtian of the Upper Cretaceous, but the Cretaceous–Paleogene boundary (K–T boundary) runs right through this formation near its top, and the uppermost parts are consequently from the Danian (Lower Paleocene). It was probably deposited around the intertidal zone, as the sedimentary rocks of this formation alternate according to sea level changes between deposits of muddy beaches and of shallow ocean.[1]
Fossil content
Dinosaur remains are among the fossils that have been recovered from the formation.[2]
Well-preserved dinosaur footprints assigned to Hadrosaurichnus australis have been found in this formation,[3] as were fossil eggs, stromatolites and the Mesozoic palynomorph Aquilapollenites. [1]
Other fossils recovered from the formation are:
- Ichnofossils
- Hadrosaurichnus australis[3]
- Salfitichnus mentoor[4]
- Taponichnus donottoi[4]
- Telosichnus saltensis[4]
- Yacoraitichnus avis[4]
