Phyllocarid?


IlmareYavanna

Recommended Posts

I recently got this fossil for my classroom museum. The seller listed it as an unidentified invertebrate. The closest I can find anywhere is a Phyllocarid type animal. Does that sound right or am I way off base?

Collection Details:

Lowermost Upper Cambrian, Mount Simon Complex, Blackberry Hill deposits
Marathon County, Wisconsin, USA

Matrix: 14 X 8.6 X 2.5 cm
'Creature': 12.2 cm long

Thanks for any help!

Can we get a close up of the fossil?

Picture is too small to make out details.

Sorry for the delay...I had to take it out of the display and rephotograph it after school.

A lot of the Mt. Simon fossils have been enhanced with water color for extra contrast.
You should contact James Hagadorn. He coauthored an excellent paper on this topic:

The paper does add credence to the site, but I'm afraid this particular one may have to be taken on faith. It looks to me like a number of alternate shapes could have been colored in as well as this. If it were an uncolored research specimen it would be easier to trust the instincts of the people working the site, but coloration by a seller I would have trouble with.

Would it help to know the seller? I've researched him, and I can't find anything that would indicate intentional misleading on his part.

Did he collect it, or is he a re-seller?

The whole thread of possession has a hand in this, and every fossil's provenience.

He is a re-seller based in England. He does have a paleontological background it appears, mainly concerning trilobites. I did find the coloration of the fossil odd, though now that the whole watercoloring thing was mentioned, it makes sense. Do you think it would help to contact the seller to see what he knows?

Is there anything besides the color to indicate a fossil is actually present? Perhaps if you take a photo with the light inclined to the specimen to bring out the surface texture something will show.

I hope these work. I used the strongest lamps in my classroom. And it is almost certainly watercolored...there was a splotch of the same color on the underside of the matrix. Even if it does turn out to be a fake, this will be a learning experience for me. Thank you to everyone who has helped so far...you guys/gals are the best!
