KompsFossilsNMinerals Posted August 3, 2021 Share Posted August 3, 2021 Hi everyone, I was at the Herkimer fossil and mineral show last week and had the chance to meet Allan Lang (owner of Langs quarry). I bought a couple of bugs off of him, but this one with the label "Old Mountain France" caught my eye. I'm not sure if it's a French trilobite or from somewhere else, but I'd appreciate any info or suggestions on what species it is. The segments in the middle were broken off, so I glued it back in place. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted August 3, 2021 Share Posted August 3, 2021 I think the first word is not 'old' but 'Ord', short for Ordovician. 'mountain' is actually Mortain, the area. Maybe. 1 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

piranha Posted August 3, 2021 Share Posted August 3, 2021 This one appears to be an unusual association of two different trilobites. The thoracic segments are oriented in the opposite direction of the 'cephalon' with the axis tapering rearward. The morphology of the segments is consistent with Ectillaenus. The cephalon is certainly an enigma! 2 Link to comment Share on other sites More sharing options...

The first post says that he glued the thoracic segments back in place - could he have done it backwards?

I don't know, it looks more like a composition, and not an association. I see it too strange. In addition, I see differences in the erosion, much more accentuated, in the piece of the cephalon.

The puzzle pieces fit together well. Note that a few of the segments are visible under the mystery element. There is also a possibility we are looking at an optical illusion: an unusual fracture and repair that looks similar to the outline of a cephalon with large sweeping genal sines. A pygidium would be a better explanation than a cephalon completely devoid of any diagnostic features. 1 1 1 Link to comment Share on other sites More sharing options...
Kane Posted August 3, 2021 Share Posted August 3, 2021 I agree. To my eye, we are likely looking at a pygidium, and so an illaenid seems an optimal guess. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

I think that theres a slight chance I might have glued it backwards, but I believe that the way I glued it fit better than the other direction 36 minutes ago, Paleorunner said: Hello.

I also included some more photos of other angles of the enigma trilobite, along with some close ups.

piranha Posted August 3, 2021 Share Posted August 3, 2021 The new photos are much better! Thoracopygidium: Ectillaenus sp. 3 1 Link to comment Share on other sites More sharing options...
piranha Posted August 3, 2021 Share Posted August 3, 2021 The last four photos capture the proper lighting and perspective, but the other three photos are even more illusory. This trilobite should get an honorable mention as a particularly peculiar (and cruel) optical illusion! 2 Link to comment Share on other sites More sharing options...
