Plantguy Posted May 19, 2019 Share Posted May 19, 2019 (edited) So I was rooting again around in the garage and found a couple plates I had bought a few years back and never tracked down an ID for. Tentative provenance was Paleocene from Montana. I found this article recently and was wondering if it could be one of the genera/sp described or one of the other genera mentioned in the discussion section. Trapa, Trapago, Fortuna, Quereuxia. STOCKEY, R. A., AND G. W. ROTHWELL. 1997. The aquatic angiosperm Trapago angulata from the Upper Cretaceous (Maastrichtian) St. Mary River Formation of southern Alberta. Int. J. Pl. Sci. 158: 83-94. Can be found here: https://www.researchgate.net/publication/240563741_The_Aquatic_Angiosperm_Trapago_angulata_from_the_Upper_Cretaceous_Maastrichtian_St_Mary_River_Formation_of_Southern_Alberta I also was looking at the USGS pub 375 https://pubs.usgs.gov/pp/0375/report.pdf My plates have a number of leaflets and fragments with very little venation visible and in a pale gray and a light pink color in a very fine matrix.....Many of the leaflets have small teeth... Plates: Crenulations Leaflets and partial venation Anyone have any expertise in these? Looks like the authors were indicating more study is needed in this area of aquatic plants--that was 20 years ago. Any help is appreciated. Thanks! Regards, Chris Edited May 19, 2019 by Plantguy Forgot the USGS info as well...dang.... 1 Link to comment Share on other sites More sharing options...
daves64 Posted May 19, 2019 Share Posted May 19, 2019 Those look like they could have inspired the old Japanese silk prints. Actually very pretty. Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...

Yes they do have a very cool and calming look to them. The symmetry is pretty neat as well.. From the USGS pub ref above. Regards, Chris Link to comment Share on other sites More sharing options...
Bronzviking Posted May 19, 2019 Share Posted May 19, 2019 I can't help you Chris but what a pretty plate. The leaflets look like pink flowers. Definitely mother nature at work! Link to comment Share on other sites More sharing options...
JohnBrian Posted May 20, 2019 Share Posted May 20, 2019 There is a non-aquatic extant bush that has leaves similar (kind of pointy on the sides) to that but I don't know the name of it. ---------------------------------------------------------------------------- John I had a friend once, but the wheels fell off.

Thanks! Yeah I should go back to square one and not assume aquatic plant as was proposed and start going thru some basic ID decision chains....I wish I could see some clear venation...maybe I need to try prepping some of these areas to see what comes up...I can see what I think looks like a very small gastropod in one area and another plant like shape that almost looks like some type of frutification/seed...may be some clues in the stem attachments as well as other appendage forms.

Plantguy Posted May 20, 2019 Author Share Posted May 20, 2019 Hey Scott/Tim---do either of you have any similar material in your collections or recognize these? Thanks. @piranha @paleoflor Regards, Chris Link to comment Share on other sites More sharing options...
Plantguy Posted May 26, 2019 Author Share Posted May 26, 2019 Hey Gang, I've been able to confirm an ID for these guys. Turns out they are Quereuxia. I'm told that name Trapago applies, but the older name with priority for those leaves is Quereuxia. The reference explaining this: JOURNAL ARTICLE On the Nomenclatural Status of the Morphogenera, Quereuxia and Trapago Leo J. Hickey Taxon Vol. 50, No. 4 (Nov., 2001), pp. 1119-1124 Quereuxia Krysht. ex Baikovskaja is the correct name for a morphogenus of leaves and leaf rosettes belonging to an aquatic angiosperm of Late Cretaceous to Palaeocene age in North America and Eurasia and must be accepted instead of its illegitimate junior synonym, Trapago McIver & Basinger Regards, Chris 6 Link to comment Share on other sites More sharing options...

I enjoy trying to find an answer/ID to satisfy this crazy curiosity thing I have and the resultant many many questions---usually its an impossible task but with you alls and with many of those in academia's patience and help I find most answers/ID's! Thank you! Special Kudos go out to all of the Florida Museum of Natural History folks--most notable Drs. Manchester, Portell and Hulbert for their help! There are still plenty of those unknown poorly preserved unidentifiable fragments that still haunt me that are in my garage and in your collections! Its still alot of fun!!
