First up is a bunch of mosasaur paddle bones. Judging by their preservation, they're from Kansas, Niobrara Formation (Coniacian through Campanian), most likely the Smoky Hill Chalk Member. It's unclear whether the bones are associated, but I've determined them to consist of a right femur and fibula and phalanxes (identification is complicated by the shortage of good comparative examples in accessible literature as well as the paucity of mosasaur skeletons in European museum displays, let alone with well-preserved and unaltered hind paddles). Based on those assumptions, it doesn't seem impossible for the bones to have been found together, and belong to the same rear flipper. The second piece is a paddle bone of an ophthalmosaurid ichthyosaur. The seller suggested the Sundance Formation as possible provenance, which would make it Middle to early Late Jurassic (Bathonian through Oxfordian) in age. This is my first but if American ichthyosaur! Finally, there's this rooted crocodile tooth, measuring near 1.9 cm. Possibly Aguja Formation, making it Campanian in age. Very nice fossils! I especially like those Mosasaur paddle bones. -@fossilhunter21 1 Link to comment Share on other sites More sharing options...

I finally found a copy of Index Fossils of North America by Shimer and Shrock that I was willing to pay for. Most of the copies I have come across were, in my opinion, too expensive for their condition. The spine of this one needs some love, but the book is complete. With a little attention on my part it should serve me well. I found a copy a while back at a price that I didn't mind, which is ex-Beloit College library in Wisconsin. Similar condition but missing the spine. Also an odd feature in that p.629/630 is inserted between p.214/215. Anything like that in yours? One of these days I'll find a bookbinder to repair it, but not sure if a single leaf can be moved to a different place in the book (hope so).

Wrangellian Posted February 1, 2022 Share Posted February 1, 2022 Still, you normally only see the carapace (in my experience), so that's a bonus. Link to comment Share on other sites More sharing options...
MarcoSr Posted February 1, 2022 Share Posted February 1, 2022 I received two different packages in the mail yesterday. One contained this really nice small slab (3.5 inches) of petrified wood in the below pictures. There wasn't any data with the slab, so I've sent an e-mail to a petrified wood expert with a number of close-up pictures of the wood structure to see if he might have an opinion on the wood type and where the slab is from. EDIT: The piece is a vesselless dicot from the Pacific Northwest. The second package contained 11 different stromatolite, banded iron and speleothem slabs. By far, the nicest and rarest slab is the domal bulbous stromatolite slab in the picture below: Stromatolite, Kona Dolomite, domal bulbous, Precambrian Paleoproterozoic 2.2 to 2.3 BYA, Lindberg Quarry near Ishpeming, Marquette Co., Michigan (1323g 11.75x7.375x.31 inches).

I’m no bookbinder, but from what research that I have done into book repair, moving a page could be an easy task or a more difficult one. Depending on if the page fell out of the block and was glued back in the wrong place or if it was bound that way originally. I’ve got it on my to-do list to consult with my local library and/or University to get their opinion on my book. If they don’t do repair work themselves, I figure they might be able to suggest someone. Maybe you could check with your local Library/University? I’m fairly certain that I could improve the book myself, but if there is a professional near by, I’d prefer fo let them tackle the job.

Misha Posted February 4, 2022 Share Posted February 4, 2022 Got some Eifelian brachiopods from Poland yesterday. I have already got some from this area and time period, but these are free of matrix and have absolutely gorgeous preservation and detail, somewhat unlike the others I have purchased. This first is a spiriferid, Eleutherokomma diluvianoides, it shares many similarities to other spiriferids from this time from around the world but the preservation is gorgeous and this is a new genus and species to my collection. This beauty is Xystostrophia or Schellwienella umbraculum. A gorgeous strophomenid, that is also completely new to my collection. Finally, this is my favorite piece and what pushed me to purchase the entire lot. This is Schizophoria schnuri with what the seller called a "coral" attached, although to me this looks much more like another brachiopod, craniiform, specifically. I haven't gotten confirmation of that, but it's quite similar to another specimen I have. I absolutely love brachiopods with other organisms on them, as I think it tells a really interesting story, makes for a much more unique piece and tells us more about the world these ancient organisms lived in. I looked a bit deeper and apparently, these Skaly beds where these fossils come from used to be quite close to other Devonian beds like in North America at that time, which could account for the similarities we see in these brachiopods with those that are found here. All in all, I just found these pieces fascinating and beautiful. 3 6 Link to comment Share on other sites More sharing options...

Paleorunner Posted February 4, 2022 Share Posted February 4, 2022 @Misha What cute brachiopods. I have some just like it, even my Schizophoria has the same organism attached.

That's a nice specimen! and it seems that we got the spiriferids from the same source as mine has the same type of label with it. The encruster on your Schizophoria looks like it might be a tabulate coral? Maybe something like Aulopora sp.? Link to comment Share on other sites More sharing options...

I also thought the same when I saw the spirifer. - It may seem strange, but I thought it was something similar to this type of current anemone. ( sea fig ).

Joe_17 Posted February 5, 2022 Share Posted February 5, 2022 Today I got another Giant ground sloth claw. This one is from Bolivia, from an old collection. I suspect it to be Mylodon darwinii , but it might be Megatherium americanum. 4 Link to comment Share on other sites More sharing options...
