Lescuropteris

This morning I have found some plates with fern leaves and thin stems (rachis). When I looked on them through my scope I noted that I found the Lescuropteris leaves which is very close to Odontopteris.

Roman... For me to be sure with the ID's I always get a hand lens, the plant reconstruction diagram and the fossil and sit down and compare the similarities... and its still a very difficult task to do... and when you think about part formed leafs and the variations in leafsize on the same plant it all becomes a bit confusing lol...so I trust your judgement...Very nice fern plates and photo's... ;)

Cheers Steve... And Welcome if your a New Member... :)

Thank you Steve, I have had some difficulties with ID, but I think that is Odontopteris type fern in any case.

Hi Steve, I am still not sure about that fern ID. I see quite unusual petternation on the leaves I called Neuropteris. Some more close ups just to think :)

Unusual petternation

Leaves I would call Odontopteris (poss. Lescuropteris)
