Summary

Description
English: Historical map of the Joggins sea cliff at Coal Mine Point (Hardscrabble Point), Nova Scotia, including low ridges (“reefs”) which extend from the cliff front into the tidal flat of the Chignecto Bay. These “reefs” are erosional remnants representing those beds within the sedimentary succession of the Joggins Formation which are most resistant to erosion (at the Joggins Cliffs in most cases, as well as at Coal Mine Point, these are sandstone beds). From the ridge labelled as “Lesser Reef” in the map, John William Dawson and allies recovered 25 fossil tree stumps of lycopod trees in 1877, 15 of which contained fossil remains of land vertebrates (tetrapods).
Deutsch: Historische Karte der Joggins-Kliffküste bei Coal Mine Point (Hardscrabble Point), Nova Scotia, einschließlich der niedrigen Felsenrippen („Riffe“), die sich von der Klifffront in das Watt der Chignecto Bay erstrecken. Bei diesen „Riffen“ handelt es sich um Erosionsreste, die die erosionsresistentesten Schichten in der Abfolge der Joggins-Formation repräsentieren (in den meisten Fällen, so auch am Coal Mine Point, sind dies Sandsteinschichten). An der als „Lesser Reef“ beschrifteten Rippe gruben John William Dawson und Mitarbeiter im Jahre 1877 25 fossile Baumstümpfe von Bärlappbäumen aus, von denen 15 Überreste von Landwirbeltieren (Tetrapoden) bargen.
