Zone J - Canoa Formation (Pliocene to of Ecuador)

Also known as Cancellaria Zone

Where: Manabi, Ecuador (0.2° N, 80.3° W: paleocoordinates 0.0° N, 79.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Canoa Formation, Piacenzian to Piacenzian (3.6 - 1.8 Ma)

• As exposed in the Quebrada Mangle section, the Canoa Formation has a thickness of around 125 feet, comprising Pliocene through Pleistocene marine and non-marine strata. The collection is from the basal Zone J (Cancellaria Zone), which has a thickness of around 50 ft.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; unlithified, concretionary, shelly/skeletal, blue, carbonaceous sandstone and claystone

• No environmental data reported. Presumably shallow water.

• Massive to well-bedded blue sands and clays. Some of the sands are quite carbonaceous. In the upper part the sands are quite nodular.

Size class: macrofossils

Collection methods: quarrying,

• Probably collected by current authors, though text also makes referal to faunal lists by Sheppard (1930) and a collecton of Barker.
