Fissiletag Posted January 11, 2023 Share Posted January 11, 2023 I'm looking at purchising a fossil that is labeled anomalocarid. It's not super well preserved, but looks like part of an anomalcarid arm. Is it an anomalocarid or something else. Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 11, 2023 Share Posted January 11, 2023 Not sure there is enough of it there to say one way or the other.

Fissiletag Posted January 11, 2023 Author Share Posted January 11, 2023 The main thing I'm looking at are these spines coming off of the arm. Is there anything else in the Chengjiang fossils that would have those spines? Here's a photo of a sold fossil that looks sort of similar also labled animalocarid. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted January 11, 2023 Share Posted January 11, 2023 Maybe this is Anomalocarid, but not arm ? Link to comment Share on other sites More sharing options...
Fissiletag Posted January 11, 2023 Author Share Posted January 11, 2023 @Rockwood Any reason for it not being an arm, and if it isn't what part could it come from? 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 11, 2023 Share Posted January 11, 2023 Not sure that is a spine. Too hard to tell, in my opinion. It could be. Maybe. I would personally wait for a more easily identifiable specimen. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Which end would be the distal one ? That's why it doesn't seem to quite add up to an arm. 1 Link to comment Share on other sites More sharing options...
Fissiletag Posted January 11, 2023 Author Share Posted January 11, 2023 @RockwoodI think the arm is going this way if it is an arm. Link to comment Share on other sites More sharing options...
bcfossilcollector Posted January 11, 2023 Share Posted January 11, 2023 It does look like the grasping appendage of an Anomalocarid. However, I agree with the uncertainty expressed by Fossildude and Rockwood. The second image you’ve provided leads me to believe that it could be a grasping part of an Anomalocarid. Very interesting specimen! 1 Link to comment Share on other sites More sharing options...

I can't see it comparing well with the other example. The fossil does seem to extend in that direction, but it looks more flattened and less segmented. 1 1 Link to comment Share on other sites More sharing options...
Fissiletag Posted January 11, 2023 Author Share Posted January 11, 2023 @Fossildude19 I probably will purchase it because it is extremely cheap, and if another one that is easier to identify goes up for sale I might look at getting it. Link to comment Share on other sites More sharing options...
bcfossilcollector Posted January 11, 2023 Share Posted January 11, 2023 Just now, Rockwood said: I can't see it comparing well with the other example. The fossil does seem to extend in that direction, but it looks more flattened and less segmented. I agree. I see a few morphological similarities with the second example but the specimen in question is very faint. Could be a variation in preservation, or perhaps a different type of Anomalocarid. Could also be something else! Interesting for sure. 1 Link to comment Share on other sites More sharing options...

Mahnmut Posted January 11, 2023 Share Posted January 11, 2023 Hi Fissiletag, to me it looks good, especially when looking at my monitor obliquely, which brings out the contrast in absence of photoshop. Faint preservation, but for a possible anomalocaridid at a good price I´d risk looking at it in person.
