The Attawapiskat Formation of the Hudson Bay and Moose River basins (Fig. 1 A) provides an ideal opportunity for studying post-extinction recovery and subsequent diversification of reef-dwelling shelly benthos during the early Silurian as it not only contains abundant, diverse, and well-preserved brachiopods (Jin et al., ), but also exhibits the .

Hi there, Ammonight! As Kane has said, there are some waterways out here in the western part of the GTA that are okay for collecting fossils - my daughter and I have checked out Humber River and Etobicoke Creek and we've found orthoconic nautiloids, bryozoans, brachiopods, corals, bivalves, gastropods, and a beat-up trilobite.

The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period), and they flourished throughout the. The trilobite faunas considered here are from the Telychian (Llandovery, Silurian) reefs of North Greenland ().The reef tract, which extends some km along strike, is exposed across North Greenland (Sønderholm and Harland, ).It represents the oldest large-scale reef development in the Silurian, and is the most extensive of the late Llandovery reef.

Silurian trilobites from the northern Yukon Territory.

Lifestyles of trilobites: the painting shows how trilobites from different periods lived in the sea. In shallow waters amongst the bivalves (1), crinoids (2), algae (3) and gastropods (4), the faunas were large, but of low diversity, e.g.
Flexicalymene (5). Intermediate faunas were more diverse— Selenopeltis (6), Geragnostus (7), Chasmops (8) and Remopleurides (9) lived alongside.
