MarcusFossils Posted July 27, 2015 Share Posted July 27, 2015 Hello fellow fossil hounds! Just picked these up in a truly wonderful shop in Lacombe, Alberta, Canada. I think they're from the Ordovician of Craigleith, Ontario, Canada. Pseudogygites latimarginatus? Same Id for both? The labelling was a bit unclear... 1. 2. Have a great day, and thanks in advance for any and all responses!

FossilDAWG Posted July 27, 2015 Share Posted July 27, 2015 The bottom photo shows several pygidia of Pseudogygites latimarginatus. It could be from Craiglieth, or the Ottawa area, or the Oshawa/Bowmanville area (all in Ontario). This is an Upper Ordovician species. The top photo looks like Asaphiscus wheeleri, which is common (second only to Elrathia kingi) in the Antelope Springs, Utah area (Middle Cambrian). These trilobites are quarried at U-Dig Fossils and other pay-to-dig quarries in the area. If you look closely you may find examples of Elrathia and other trilobites (Peronopsis for example) on or in the slab. Don Link to comment Share on other sites More sharing options...
Guguita2104 Posted July 27, 2015 Share Posted July 27, 2015 Great!I'm not an experte in trilos, but the second seems a Pseudogygites latimarginatus (as you said)...I especulate that because of the cefalon shape, the number of pleuras and the pygidum format.

Eocenecarnage Posted July 27, 2015 Share Posted July 27, 2015 The bottom picture does seem to be a Pseudogytes, but being an expert in Cambrian trilobites, that top one is definitely (I mean definitely) an Asaphiscus wheeleri. Link to comment Share on other sites More sharing options...
Malcolmt Posted July 27, 2015 Share Posted July 27, 2015 The pseudo looks more like the matrix I have seen from Craigleith than Bowmanville, but definitely a pseudo Link to comment Share on other sites More sharing options...
