Poty Quarry, 11 m above K/Pg boundary (Paleocene of Brazil)

Also known as Guarinisuchus munizi type layer

Where: Pernambuco, Brazil (7.9° S, 34.9° W: paleocoordinates 11.8° S, 20.9° W)

• coordinate stated in text

• small collection-level geographic resolution

When: P2 other zone, Maria Farinha Formation, Danian (66.0 - 61.6 Ma)

• 11 m above the K/Pg boundary in the P2 biozone of the Late Danian (62-61 Mya)

• formation-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone

• Shallow marine and near-shore habitat
• All bones were found in one limestone block and were not articulated, suggesting that some transportation had taken place before the animal’s final burial.

Size class: macrofossils
