Microraptorfan Posted April 14, 2021 Share Posted April 14, 2021 I thought I would ask here, do any of the members here have Mesozoic gar fossils in their collection, im not looking to buy them, more wanting to see the range of Mesozoic fossil gar material owned by members here Link to comment Share on other sites More sharing options...
jpc Posted April 15, 2021 Share Posted April 15, 2021 Gar scales are among the most common small fossils in the Lance Fm (Maastichtian) of Wyoming and Hell Creek of Montana. I have thousands of them. There is one articulated gar that I now of from the Hell Creek, now at the Field Museum in Chicago. Link to comment Share on other sites More sharing options...

Is this a mysterious unpublished specimen? That sounds like a tall tale of a fish tail...

RJB Posted April 15, 2021 Share Posted April 15, 2021 Hey @jpc, May I ask what one does with 1000's of gar scales? I have found two rotten gars whilst digging for fish but left all the scales. RB Link to comment Share on other sites More sharing options...

piranha Posted April 15, 2021 Share Posted April 15, 2021 Hopefully JP is correct and this specimen was purchased by the Field Museum. We should be looking forward to the inevitable upcoming publication by Lance Grande, but according to this <LINK> the 3D scan was uploaded six years ago by the company that sold it. I can't imagine that six years later that magnificent 3D scanned specimen is languishing at FMNH ... and Lance Grande has not formally published it yet? If it resides in a private collection, then unfortunately it is lost to science. Link to comment Share on other sites More sharing options...
piranha Posted April 15, 2021 Share Posted April 15, 2021 Lance Grande has just replied: this specimen is not in the FMNH collection. That would explain how it has mysteriously elluded any formal description. 2 Link to comment Share on other sites More sharing options...
jpc Posted April 15, 2021 Share Posted April 15, 2021 The one I am referring to was found at the site in North Dakota that preserves sedimentary evidence of the KT extinction bolide impact. I can't remember the name of the site, but when I was at the Field a few years ago, we got a tour of the lab and there was a large jacket containing at least one paddlefish and one gar from that site. I imagine these were donated to the Field, and Lance MUST know about them. If he was referring to the specimen in the photo above, I am pretty sure that is not the one I am talking about. But that one is a really nice specimen and CT scan. Link to comment Share on other sites More sharing options...

Microraptorfan Posted April 15, 2021 Author Share Posted April 15, 2021 I emailed the website apparently it was acquired by the Royal ontario museum not the field museum 3-4 years ago 1 Link to comment Share on other sites More sharing options...
piranha Posted April 15, 2021 Share Posted April 15, 2021 Lance Grande has replied with additional clarification: FMNH does not have any articulated gar specimens from Hell Creek. Link to comment Share on other sites More sharing options...
jdp Posted April 15, 2021 Share Posted April 15, 2021 There are also some articulated gars from the Upper Cretaceous of Alberta. I'm not sure if they've been published on but they definitely exist. Link to comment Share on other sites More sharing options...

The Tanis specimen posted above is not a gar. It is a paddlefish and sturgeons. ***So we are back where we started with a single mysterious unpublished specimen, reportedly purchased by the ROM and awaiting formal publication (we hope!). 2 Link to comment Share on other sites More sharing options...
jdp Posted April 16, 2021 Share Posted April 16, 2021 IIRC, the specimen in question was collected by Anthony Maltese at the RMDRC: http://rmdrc.blogspot.com/2013/10/actractosteus-from-hell-creek.html RMDRC is a pretty legit operation which works closely with museums to prioritize getting specimens into public repositories, so if they say it is at the ROM, that is trustworthy. I don't think there's anyone at the ROM who would be prioritizing work on this specimen, but my guess is that it was purchased with the intention of being part of their public displays. 1 Link to comment Share on other sites More sharing options...
jdp Posted April 19, 2021 Share Posted April 19, 2021 Relevant to this thread, here is a new Cretaceous gar from Morocco: https://www.sciencedirect.com/science/article/abs/pii/S0195667121000860 Link to comment Share on other sites More sharing options...

At least I think that was at the Tyrell. edit: I just looked through my photos from my 2013 trip to the Tyrell... yes they have a boulder full of gars. The question is are they Cretaceous? Most likely given what they work on up there. Edited April 19, 2021 by jpc Link to comment Share on other sites More sharing options...

RuMert Posted May 1, 2021 Share Posted May 1, 2021 I believe it's a gar tooth, looks similar to modern gar teeth. But it's uncertain unlike the provenance which is 100% Middle Tithonian My sites & reports Link to comment Share on other sites More sharing options...
