Point Lepreau (Pleistocene of Canada)

Where: New Brunswick, Canada (45.1° N, 66.5° W: paleocoordinates 45.1° N, 66.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Middle Pleistocene (0.8 - 0.1 Ma)

• bed-level stratigraphic resolution

Environment/lithology: glacial; unlithified, red claystone and unlithified sandstone

• Beginning about 14,000 years ago glacier ice retreated from New Brunswick leaving most of the province ice-free by 12,000 years B.P. Proposed ice margins from 14,000 to13,000 vary widely between authors, but some place the glacier front near the present New Brunswick, Bay of Fundy coast 13,500 to 13,000 years ago.
• Quaternary marine clays form thick red deposits interbedded with sandy layers

Size classes: macrofossils, mesofossils

Collected by M. Fairweather and M. Mersereau

Collection methods: bulk,

• Collection resides at the New Brunswick Museum
