The Dishman Quarry Preserve The rock below holds an excellent imprint of the bark of the Lepidodendron tree;
the diamond shaped pattern
represents the scars from leaves that were shed, with each diamond representing
the base of a leaf. See http://museum.gov.ns.ca/fossils/gallery/specimen/982131.htm for more information.
Striations on the rock, visible with the naked eye, represent a twice-daily
tidal deposit of sediment with a continuous record of 10yrs, making it
the 2nd longest continuous tidal record in the world, after a 30-yr site in
Australia.
Persons interested in visiting this site should contact the SLT office or
property Steward. |
