DatFossilBoy Posted March 23, 2018 Share Posted March 23, 2018 Hey all. I saw this fossil arthropod online for a really low price and the seller claims it’s a « super rare arthropod Bradoriida » from Mongolia. Is it really what it sais and is it really that rare? Worth it? Here are some pictures of it. Thanks for all the help. Cheers Link to comment Share on other sites More sharing options...
oilshale Posted March 23, 2018 Share Posted March 23, 2018 Bradoriida are interesting species but not especially rare. This fossil is from Chengjiang, Yunnan in China and not from Mongolia.

gigantoraptor Posted March 23, 2018 Share Posted March 23, 2018 Looks a lot like Kunmingella douvillei or a similar species. These are not too rare. It looks a lot like the Maotianshan Shales in Chengjiang (Yunan province in China). Link to comment Share on other sites More sharing options...
caldigger Posted March 24, 2018 Share Posted March 24, 2018 Two things that do not generally go together. Super Rare and Super Cheap. If it is truly that rare, why would they be selling it for so little? 2 Link to comment Share on other sites More sharing options...

If it is truly that rare, why would they be selling it for so little? Because maybe its in relatively bad condition. Also just because something is rare, that doesn't mean its worth heaps. 1 Link to comment Share on other sites More sharing options...
DatFossilBoy Posted March 24, 2018 Author Share Posted March 24, 2018 Okay. Thanks for the help. I think the seller is a bit exagerating,will pass this one. But Foozil has a point. Thanks everyone. Link to comment Share on other sites More sharing options...
