• U-Pb SHRIMP date of 147 ± 0.1 Ma from ignimbrite at base of measured section, just below fossiliferous layer

•
•The succession of clastic sedimentary rocks with intercalated tuffs is 300–320 m thick. The dinosaur fossils occur in an approximately 100 m succession of alternating green volcaniclastic pebbly sandstones and sandy sedimentary breccias, with intercalations of lapilli tuffs and red ignimbrites with eroded tops The succession of clastic sedimentary rocks with intercalated tuffs is 300–320 m thick.
