mariont Posted March 2, 2015 Share Posted March 2, 2015 Hello, this was found in Manitoba. It is about 4"long and 4" in diameter. This piece had weathered out and there was at least another 4 - 6" encased in stone. The interior has crystallized. Is it a straight nautiloid? Any assistance would be appreciated. Thanks!

Auspex Posted March 2, 2015 Share Posted March 2, 2015 Maybe a great big re-crystallized horn coral?

abyssunder Posted March 2, 2015 Share Posted March 2, 2015 I think is a re-crystallized coral part from a coral colony.

TheCounts Posted March 2, 2015 Share Posted March 2, 2015 It's a corallite, a single organism of a coral, the colony. Anyway it's a really nice piece! (maybe a fasciculated coral?) Link to comment Share on other sites More sharing options...

FossilDAWG Posted March 3, 2015 Share Posted March 3, 2015 Can you be any more specific than just "Manitoba" for the locality? There is a lot of Ordovician (Winnipeg, Red River, Stoney Mountain, and part of the Stonewall formations), plus several Silurian and Devonian formations in the Interlake area. All those formations are exposed at places along the shore and islands in Lake Winnipeg and Winnipegosis. The style of preservation reminds me of some of the upper members of the Stoney Mountain, the Stonewall, and some of the Silurian Interlake Group formations. A more specific locality could help narrow down the age. I know of a couple of Silurian corals that look a bit like that, but they are much smaller (the corallites are only 2-4 mm across).

mariont Posted March 4, 2015 Author Share Posted March 4, 2015 Hi Don, it was found in the Hecla Island area (west shore of Lake Winnipeg). Link to comment Share on other sites More sharing options...
