I took some time to walk along the river on campus. The river levels have receded significantly since the heavy rains and snow melt of more than a week ago.
What the area looks like now that the floodwaters have receded. Plenty of transported river debris, mostly local area (Dundee) limestone, but also glacial till and other things.
A brachiopod on a piece of old flooring, and a coral. Plenty of coral pieces (colonial and horn) to be found.
Trilobite fragment impression
Brachiopod impression at the top. Below that an interesting trace/impression on black shale. From left to right at the bottom: water worn spirifer, high-spired gastropod steinkern, and a small hash containing a fragmentary trilobite pygidium.
The nearest Ordovician outcrops are hundreds of kilometres away, and yet here are some very well-traveled and worn Ordovician shale containing the cranidia and moulted bits of Triarthrus.
Shiny shell hash.
A healthy sized Triarthrus cranidium.
Top left is plump, thick-ribbed nautiloid, top right are the trilobite fragments, and below are water-worn brachiopods (one which has a nice calcite crystal inside).
