GHM Posted November 25, 2016 Share Posted November 25, 2016 I am looking for some information on a fossil I inherited from a family member. I really know nothing regarding fossils in general, so any information is helpful! Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 25, 2016 Share Posted November 25, 2016 Hello, and Welcome to the Forum. The trilobites look like Pseudogygites sp, and Triarthrus sp. to me. Do you know where they were found?

Jeffrey P Posted November 25, 2016 Share Posted November 25, 2016 Any idea where those might be from? If Tim is right with the IDs then they are likely to be Ordovician. That is an unusually large number of partial trilobites for one rock. Link to comment Share on other sites More sharing options...
Kane Posted November 25, 2016 Share Posted November 25, 2016 Hm. I've never disagreed with Tim before, but those look somewhat different than Pseudogygites latimarginatus, where the pygidial margins tend to be thicker and the terminal axial piece has a bit more flaring, like the horn of a bugle. Can you tell us where you found it? 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 25, 2016 Share Posted November 25, 2016 Kane, I see what you are saying. They don't quite match up, do they? Any ideas on what else it could be? Maybe @FossilDAWG can have a look, and enlighten us. Don, where are you??

GHM Posted November 25, 2016 Author Share Posted November 25, 2016 The gentleman I received them from past away a number of years ago so unfortunately I have no idea where they came from. I am in Western Canada so I assume it is from somewhere around here... Link to comment Share on other sites More sharing options...

piranha Posted November 25, 2016 Share Posted November 25, 2016 These are Middle Cambrian trilobites from the Mt. Stephen trilobite beds (Burgess Shale). Although collecting has been prohibited for many years, there are actually quite a few specimens floating around in private collections. Ogygopsis klotzi and Zacanthoides romingeri appear to be the two species present on your slab of matrix. 3 Link to comment Share on other sites More sharing options...
FossilDAWG Posted November 25, 2016 Share Posted November 25, 2016 Hi Scott, I agree with your suggestions. I am puzzled, though, by the black shale-looking matrix. Everything I have seen from Mt. Stephen is on a light tan-colored matrix. I wonder what the source of these fossils was. Don Link to comment Share on other sites More sharing options...

Unfortunately the precise collecting locality data is vague. Link to comment Share on other sites More sharing options...

According to Deiss 1940, these are the different matrix types for the Ogygopsis fauna at Mt. Stephen: "When the Mount Stephen section was examined in 1939 several surprising facts were discovered. The Ogygopsis fauna occurs in several different kinds of matrix: brown soft platy calcareous finely arenaceous shale in the upper beds; green tan platy harder shale in the underlying beds; black-gray calcareous shale beneath the green and tan interval; and white-buff soft slightly calcareous clay-shale at the base."

ynot Posted November 26, 2016 Share Posted November 26, 2016 The fossil forum does not allow appraisals. I never think of value $ wise, I just like good fossils.

No, they are not proetids. Ogygopsis and Zacanthoides each belong to the Order: Corynexochida 3 Link to comment Share on other sites More sharing options...
