Bree Posted September 18, 2016 Share Posted September 18, 2016 Hi I have just begun collecting fossils and I still have a lot of trouble telling the difference between what is real and what is fake. I am thinking about purchasing a Moroccan Phacops Trilobite (picture below) and I was wondering if anyone could give me advice as to it's authenticity. Thank you Link to comment Share on other sites More sharing options...

DPS Ammonite Posted September 18, 2016 Share Posted September 18, 2016 The devil is in the details. Ask for better close-up photos, including the eyes. Note the crude scratches surrounding the trilobites in comparison to the nearly perfect trilobite. The scratched surface sometimes covers up the contact where a phony trilobite is set into a rock with a carved hole in it. Beware. My goal is to leave no stone or fossil unturned.

doushantuo Posted September 18, 2016 Share Posted September 18, 2016 Not everything needs to be fake,if you don't see what you usually see:there is e.g. a specimen known of Nephalicephalus beebei with three enlarged thoracical rings. That's a known as a teratology,a developmental aberration. Link to comment Share on other sites More sharing options...
Bree Posted September 18, 2016 Author Share Posted September 18, 2016 There seems to be detail in the eyes when I zoom in on the picture but I'm still not sure if it's real. Link to comment Share on other sites More sharing options...
doushantuo Posted September 18, 2016 Share Posted September 18, 2016 All the individual lenses might be hard to fake,come to think of it Historical Biology piece(co-authored by Clarkson,of course): horvathSurveyTrilobiteEyes_HB.pdf Link to comment Share on other sites More sharing options...

doushantuo Posted September 18, 2016 Share Posted September 18, 2016 Best of all is knowing the subject matter.Any thesis or journal article will provide plentiful details(to an annoying degree of exactitude)of the morphology of a genus . http://www.senckenberg.de/files/content/forschung/projekte/igcp-596/cronier_francois_2014.pdf (Posting this article because it might give clues to things like facies control,biogeography,etc) Link to comment Share on other sites More sharing options...

piranha Posted September 18, 2016 Share Posted September 18, 2016 Here are the larger versions of the thumbnail images. The seller's name: "Phacops corconspectans" is false. That name has never been assigned to any trilobite. The trilobite is a common Moroccan phacopid: Drotops megalomanicus Some parts have been restored. It's a typical average grade specimen. This example is priced fairly as a decent representation of the species. Link to comment Share on other sites More sharing options...
