Hi everyone, This fossil has always bothered me because of the way it felt in terms of weight and the cleanliness of the cut (there looks to have been some stabilizer added from the side, which I guess helps the case for authenticity). I only have one other fossil - what appears to be what was a very commonly sold Nemiana simplex - from a nearby region with a similar geology, and I could very well be wrong because it is indeed quite similar, albeit lighter with a more uniform grain. Since they're both Ediacaran in age and commercially not rare per se, I've always wondered if this Kimberella was legit given a fluctuating price tag that has been quite high in the past but seems to have levelled out in the mid range. As someone who once taught a diversity of life course, I am an absolute sucker for fossil items that include key moments in history, as well as evolutionary transitions. I've included pictures of the Kimberella in question, as well as a couple of items I place it next to because I'm a giant nerd and I like to imagine that this is the footprint left by some sort of mono- or poly-placophoran ("chitons") 600 million years ago. I wish I had some "smell shelly fauna" or traces left by an Aplacophoran to illustrate the molluscan "root" but alas this is it for now. The orange fossil shell is of a monoplacophoran named Proplina grandis (Gasconade formation, Missouri, Lower Ordovician) - unconcerned about its provenance - and a modern chiton from the Philippines. I know for a fact this quite popular seller misidentified a fossil fish sold to me as a madagascan coelacanth very, very early in my building of a fossil collection; this is also a reason I'd like to know if the provenance is legitimate; I've been hesitant to deal with them since and passed on many fossils as a result I'd probably only look to add a sea pen-like fossil from the region - unlikely due to the hefty price tag and commercial rarity - but I'd like to learn more about what to look out for nonetheless. As always, thanks for any insights the community might be able to provide! Cheers Marcus p.s. And happy fathers day!

I've seen friends buy these and have been admittedly jealous. Some good ones have come up and I never felt that I could ever afford one. If I waited until I could "afford" one I'd never get one. Soooooooooo, I got myself a Christmas present. Don't ask how much, I won't admit to it. For those that don't recognize what it is, it is a Precambrian Metazoan fossil called Dickinsonia costata. The fossil is over 560 million years old. This one is 9 cm by 13 cm and the best I'll ever be able to get my hands on. Big grin on my face! Love it.
