Plantguy posted a topic in Fossil NewsFYI.....Amazing.... Abstract: A new fossil mushroom is described and illustrated from the Lower Cretaceous Crato Formation of northeast Brazil. Gondwanagaricites magnificus gen. et sp. nov. is remarkable for its exceptional preservation as a mineralized replacement in laminated limestone, as all other fossil mushrooms are known from amber inclusions. Gondwanagaricites represents the oldest fossil mushroom to date and the first fossil mushroom from Gondwana. Heads SW, Miller AN, Crane JL, Thomas MJ, Ruffatto DM, Methven AS, et al.

You should read these papers. They are very interesting: Carvalho, I.; Novas, F.E.; Agnolín, F.L.; Isasi, M.P.; Freitas, F.I.; Andrade, J.A.. (2015). "A new genus and species of enantiornithine bird from the Early Cretaceous of Brazil". Brazilian Journal of Geology 45 (2): 161–171. DOI:10.1590/23174889201500020001. Carvalho, I.; Novas, F.E.; Agnolín, F.L.; Isasi, M.P.; Freitas, F.I.; Andrade, J.A.. (2015). "A Mesozoic bird from Gondwana preserving feathers". Nature Communications 6. DOI:10.1038/ncomms8141. The discovery of Cratoavis in Brazil is remarkable because nearly all Early to Middle Cretaceous birds have been found in Laurasia (Nanantius is the only other pre-Santonian bird found in Gondwana). It'd be interesting to see if there might be any Early and Middle Cretaceous birds from North Africa and the rest of South America because we now know that the multitude of Early Cretaceous bird fossils in China was due to a Mesozoic version of Pompeii.
Here are 5 insects from the lower cretaceous; specimens 1 and 2 (pics 2a, 2b) from the Yixian Formation, Huangbangi Valley, Beipiao (~ Barremian) specimens 3, 4 and 5 from Nova Olinda, Crato Formation, Brasilia (upper Aptian / lower Albian) Length: specimen 1 = 10 mm (body length) specimen 2 = 8 mm (head to the end of the longest wing) (Diptera?) specimen 3 = 10 mm (body length, head - tail) specimen 4 = 21 mm (total length) (Orthoptera) specimen 5 = 18 mm (total length) (Beetle: Dystiscidae?) Any suggestions are appreciated! (specimen 4 is a grasshopper, specimen 5 a beetle; but is it possible to say more about them?) An additional question: The small circular fossils which look like small bivalves on the Yixian specimens are conchostracans (Nestoria pissovi), but I wonder about the brownish striations on the Nova Olinda material. They are suggestive of trace fossils, but otherwise they seem to show some organic matter similar to the body fossils.They are extremely common on the plates with Crato fossils. Does someone know what they are? Thank you very much! araucaria1959
