paleoflor Posted March 17, 2010 Share Posted March 17, 2010 (edited) Really liking all the material posted in the Carboniferous plant fossil topic, I started wondering about the Mesozoic treasures collected. Please show your Mesozoic plant fossils (the stuff dinosaurs ate, haha)! I'll kick-off by showing some of my Gondwana material from the Nymboida Coal Measures (Triassic of NSW, Australia). (1) Cladophlebis gondwanica Frenguelli, 1947 (2) Dicroidium cf. odontopteroides var. remotum (Szajnocha) Retallack, 1977 (3) Dicroidium sp.?

RCFossils Posted March 18, 2010 Share Posted March 18, 2010 This is a pair of Cretaceous aged palm fronds from the Lance Formation of Wyoming. They were found last year by a friend of mine. I purchased the fossil and am having them prepared. I should be picking the piece up next week. I have seen a lot of Eocene aged Green River fronds but this is the first Cretaceous aged frond that i have seen. Link to comment Share on other sites More sharing options...
Terry Dactyll Posted March 18, 2010 Share Posted March 18, 2010 Paleoflor..... I have ony one example.... I had climbed down a fishermans rope down a pretty steep cliff looking for ammonites in North Yorkshire and a chunk of sandstone like rock caught my eye with a series of evenly spaced dots in a line along one edge.... I just gave it a 'whack' with the hammer and I discovered this.... I did some prep on it to emphasize what I think are worm borrows and preserved stem and just to tidy it up....

paleoflor Posted March 19, 2010 Author Share Posted March 19, 2010 (edited) @ RCfossils: Wow! What a beautiful specimen, just amazing. I've seen some plants from the Lance (Creek) Fm. before, but never at this scale. Please share a photo of the preparation result with us! Plant material of Cretaceous age is rather rare here in Europe. The only specimen I own is the Tempskya sp. specimen figured below. These treeferns are rather extraordinary plants though (see for example this reference) Tempskya sp. (Cretaceous) @ Terry Dactyll: Nice Zamites gigas specimen! Well worth the daredevil actions on the cliff-face in my opinion (though you might have preferred finding an ammonite, haha). I'm still planing to one day go collect in North Yorkshire. After all, it is a classic location for fossil plants of Jurassic age. What size is your specimen? Zamites gigas (as the name suggests) can grow large fronds. Just for fun, I've added another Zamites specimen here. Zamites feneonis (Pomel, 1849) Ettingshausen, 1852 (Jurassic) @ RomanK: Then please share your Devonian-Permian material, either here or in a new topic; plants of all ages are great!

Terry Dactyll Posted March 19, 2010 Share Posted March 19, 2010 Paleoflor.....The length of the frond ignoring the preserved stem at the top is 9"... so not 'too' big... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
Plantguy Posted March 21, 2010 Share Posted March 21, 2010 Gentleman, really enjoyed the views...especially like the Zamites and Dicroidium specimens! Paleoflor, I didnt realize that Tempskya was also found in the U.S. Interesting link. My collection is lacking any specimens this age at present----I've tried to snag a few off ebay but the bidding has been pretty fierce and I've been cheap!!! The only one specimen I have collected personally was a small unidentified Cretaceous Cycad leaflet from the Great Valley Sequence in Napa, California that is now in the collections in the Napa Valley Museum in Yountville, California. Again, enjoyed the thread, I wish I could contribute some photos..Regards, Chris Link to comment Share on other sites More sharing options...
paleoflor Posted March 22, 2010 Author Share Posted March 22, 2010 Hi all, Thanks for sharing the nice pictures so far! Hopefully there will be more beautiful pieces lurking in your cabinets; I'd certainly like to see more! Unfortunately I'm running out of Mesozoic material to show myself after this... Hope you'll enjoy though! Triassic: The fossils found at Nymboida (NSW, Australia) represent a Dicroidium-flora, typical for the Middle Triassic (Anisian-Ladnian) of Gondwana. These specimens come from the Farquhars Coal Seam, part of the Basin Creek Fm. The first photo shows the dichotomous division of the frond, characteristic for this morphogenus (compare with schematic from Retallack, 1977): Reconstruction of complete frond (after Retallack, 1977) and 2 Dicroidium sp. photos. Jurassic: First some specimens from the Talbragar Fish Beds flora. The site is located northeast of Gulgong (NSW, Australia) and is registered as Crown Land Reserve. The shales and siltstones (Purlawaugh Fm.) represent a Jurassic freshwater lake situated at high latitude within the Gondwanan landmass. 16 plant species are represented from this site. Note: specimens were collected in the 1980s, the area is protected and collection is illegal nowadays. Elatocladus planus (Seward) Gould, 1980 & Agathis jurassica White, 1981 Some more Jurassic plant fossils: (1) Ginkgo huttoni (Sternberg) Heer, 1876 (Yorkshire, Great Britain) (2) Otozamites feistmanteli Zigno, 1881 (Duraki, Australia) (3) Brachyphyllum nepos Jung, 1974 (Mörnsheim, Germany) Searching for green in the dark grey.

pleecan Posted March 22, 2010 Share Posted March 22, 2010 Not sure if this is from the Mesozoic era but here is a Ginko Leaf from B.C. Canada.... one of the few plant fossils in my collection.... Link to comment Share on other sites More sharing options...
paleoflor Posted March 24, 2010 Author Share Posted March 24, 2010 Not sure if this is from the Mesozoic era but here is a Ginko Leaf from B.C. Canada.... one of the few plant fossils in my collection.... Nice fossil! Never seen such a division in three lobes before. The only (famous) plant-fossil site I know from British Columbia is the McAbee flora. Don't know whether your specimen also comes from this flora (locality near Cache Creek), but it is Early Middle Eocene in age, and features two species of Ginkgo (G. dissecta and G. biloba). However, neither of these species has a description corresponding to the specimen you show here. Maybe you might be interested to take a look here. Not complete without the original articles (e.g. refs below) but still a good resource. Anyhow, really beautiful Ginkgo specimen!

palaeopix Posted March 24, 2010 Share Posted March 24, 2010 Not sure if this is from the Mesozoic era but here is a Ginko Leaf from B.C. Canada.... one of the few plant fossils in my collection.... Nope that is a Cenozoic leaf of Ginkgo from the Lower Middle Eocene of probably the Tranquille Shale (popularly known as the McAbee Fossil Beds). Could be from any of the numerous Eocene Okanagan Highlands sites located throughout British Columbia but again most likely from the McAbee site. The leaf morphology is not common to my knowledge but may be an early shoot of Ginkgo dissecta. Link to comment Share on other sites More sharing options...

paleoflor Posted July 6, 2010 Author Share Posted July 6, 2010 Hi Chris, Congrats with your purchase! It is a nice Ginkgo leaf indeed! This is a pair of Cretaceous aged palm fronds from the Lance Formation of Wyoming. They were found last year by a friend of mine. I purchased the fossil and am having them prepared. I should be picking the piece up next week. I have seen a lot of Eocene aged Green River fronds but this is the first Cretaceous aged frond that i have seen. How did it turn out to be? I'm actually quite curious to see the preparation result! Please share some photos Best regards, Tim Searching for green in the dark grey. Link to comment Share on other sites More sharing options...
Ludwigia Posted July 6, 2010 Share Posted July 6, 2010 Hi. There's some great stuff here. Since I'm a middle Mesozoic man, I've got a few things too which I can post. I already posted some Ginkgos from Whitby here: http://www.thefossilforum.com/index.php/topic/13825-the-area-around-whitby-yorkshire-uk/ And here's the rest. Credneria acuminata. Upper Cretacious. Blankenburg, Germany. I still don't know from which tree this branch might originate. I found it on a field by Geisingen, Germany. Bajocian, Middle Jurassic. Anybody have an idea? Now 2 sides of one find. Also a branch which I can't identify. Upper Bajocian, Dogger gamma, Middle Jurassic. Sengenthal, Germany. Calcite innards. Cut & polished. Best wishes, Roger.

paleoflor Posted June 9, 2011 Author Share Posted June 9, 2011 hello, Here a Pachypteris sp from the upper Jurassic, upper kimmeridgian from the right side of the river "Rhône", close to the south french Jura in France in the "bituminous limestones" length : 16 cm long Absolutely stunning specimen! Are these "bituninous limestones" full of plant fossils or are they rather rare occurrences? Do you have more specimens? I'd really like to see more on this! Searching for green in the dark grey.
