Zone H - Canoa Formation (Pliocene of Ecuador)
Also known as Loripes 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 (3.6 - 2.6 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 H (Loripes Zone), which has a thickness of around 15 ft.
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; unlithified, shelly/skeletal, blue, sandy claystone
• No environmental data reported. Presumably shallow water.
• Very fossiliferous, blue sandy clays. Many fossils.
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.
