Three Species At One Specimen

Recommended Posts

I already shared pictures from that specimen which in real one but splitted on thin plates piece of the rock. Three kind of Pteridosperm (seed fern) you can see there. One - Reticulopteris, another - Macroneuropteris (the closest I think) and last - Neuropteris sp. (Neuropterid) with very specific pettern at the pinnas.

Reticulopteris

As in your previous posts, the excellent quality of the images greatly enhances the viewer's enjoyment. Thanks.

Thank you Steve! That's from my previous trips, I just try to show the diversity of the Carboniferous "forest bed".

Hi Roman, nice specimens/photos...great find! Was going thru some of the macroneuropteris descriptions I have...lots to still learn on my part.....Whats the scale on those images...millimeters--correct??? This is a smaller specimen--they do vary a great deal?? How long is the Macroneuropteris pinnule in cm? I was also curious about trying to determine a lateral vein count at the margin...they usually branch 4 times and the larger specimens have 30-40 lateral veins per cm?

Regards, Chris

Hi Chris, yes you're right, that leaves are too small and have a different veination for the Macroneuropteris, I just mixed up some species because before I noted this (below) leaf at the same rock
