Bonnechere Caves
Eganville
The cave walls are made of limestone. This rock holds fossils of very ancient sea animals. The shells are enlarged here to help you see them.
Did you know?
These animals lived long before the dinosaurs.
Look together
Which shell makes a spiral?
An idea to try
Draw one spiral shell and one fan-shaped shell.
For the adult reading along
A little more to discover
The limestone of Bonnechere Caves dates from the Ordovician and contains marine fossils, including shells. Those organisms lived before the cave passages formed. The two drawn motifs are deliberately enlarged and stylized. They are neither scientific identifications nor a record of a particular wall.
