Hi, I would like to show you some plants that I found in the (middle probably) Bathonian of the soutwestern France, near the edge of the "Massif Central". So, I will describe the context of the find quicly : We can find some vegetals in micritic layers intercalated in sublitographic-limestone layers, very often they're fragments of lignitized wood (sometimes with a wonderful conservation and visible tracheids) but it can be reddish wood not lignitized or fragments of leaves. The first mention that I found is Monteil (1977) who indicates the discovery in a neighboring township of two leaf imprints of Otozamites sp. But this source isn't necessarily the most reliable because there are many inaccuracies or errors, but this is the only mention found this period and this area. So, for my own samples, this would be a flora from "wetlands", unusual for the french Jurassic (I believe that only one was found but a little younger, from the upper Oxfordian) and, more interesting, one (at least) of them was supposed to be Sagenopteris sp., a species of Caytoniales ("seed ferns"), never found in France. So here are the leaf imprints (or leaves) of some samples (normally the scales are correct but it is possible that I made a mistake). If someone has an identification idea or a suggestion I would be very grateful to him. 1a : Fern ? 1b 2 Fern with sporangia 3 ? 4 Fern with sporangia 5 Fern with sporangia 6 7 8 9 Fern with sporangia ? 10 Fern with sporangium 11 12 13 14 Fern ? 15
