blackmoth Posted January 18, 2015 Share Posted January 18, 2015 late carboniferous early permian Can ID the species? Link to comment Share on other sites More sharing options...
piranha Posted January 18, 2015 Share Posted January 18, 2015 With a little luck I managed to discover a very good match for these specimens. Sphenophyllum apiciserratum occurs in the early Permian floras of south China. Etymology: The specific epithet apiciserratum is derived from Latin apic- (apex) and serratus (serrate), which indicates one of the most distinct features of leaf morphology of the species.

fossilized6s Posted January 18, 2015 Share Posted January 18, 2015 Sphenophyllum emarginatum also is very common in Mazon Creek Carboniferous. If you can make out any of the veins at the base or nodes at the leaf tip, it will confirm an ID. 1 ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Ludwigia Posted January 18, 2015 Share Posted January 18, 2015 Whatever it is, it's certainly a nice, well-photographed sample! Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

blackmoth Posted January 29, 2015 Author Share Posted January 29, 2015 (edited) I tried to make the venation sharper by using low angle light. Sphenophyllum emarginatum also is very common in Mazon Creek Carboniferous. If you can make out any of the veins at the base or nodes at the leaf tip, it will confirm an ID.

blackmoth Posted January 30, 2015 Author Share Posted January 30, 2015 BTW I heard some one say it is Sphenophyllum oblong which has a lot leaf variations even on the same plant. I could not find the article ( hopefully with the pic of the found fossil) on internet yet Sphenophyllum emarginatum also is very common in Mazon Creek Carboniferous. If you can make out any of the veins at the base or nodes at the leaf tip, it will confirm an ID. Link to comment Share on other sites More sharing options...
fossilized6s Posted January 30, 2015 Share Posted January 30, 2015 I can't see the veining very much to give you a confirmed answer, sorry. Maybe being in-hand you can see more details then your picture conveys. Here's a picture of a piece i found that has the typical heart shape, crowned with multiple lobes, with the veining funneling down into one single mid vein. 1 ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
blackmoth Posted January 30, 2015 Author Share Posted January 30, 2015 The pic with low angle light reviews much more than I could see. Your pic has much sharper veins. It seems to me that there is alreay some obvious variation in your sample ( oval and lobed apex) . and the venation is very similar to what I could see on my fossil. What species is in your pic? I can't see the veining very much to give you a confirmed answer, sorry. Maybe being in-hand you can see more details then your picture conveys.

paleoflor Posted January 30, 2015 Share Posted January 30, 2015 To identify Sphenophyllum leaves, one could turn to the following criteria: (1) Length of the leaves, (2) length-to-breadth ratio of the leaves, (3) degree to which distal margins of the leaves are incised, and (4) the shape of the distal margin (entire, teeth, lobes, etc.). Your specimen shows a whorl with leaves of markedly unequal length, which is a characteristic property of Sphenophyllum oblongifolium (unless your locale has species which do not occur at the European sites where I collect, then there may be additional species -unknown to me- that have leaves of unequal length). 1 Searching for green in the dark grey.

blackmoth Posted January 30, 2015 Author Share Posted January 30, 2015 Thanks alot. Sphenophyllum oblongifolium is actually very common and dominant in the site. and I have found almost identical fossils that are ID as Sphenophyllum oblongifolium locally. To identify Sphenophyllum leaves, one could turn to the following criteria: (1) Length of the leaves, (2) length-to-breadth ratio of the leaves, (3) degree to which distal margins of the leaves are incised, and (4) the shape of the distal margin (entire, teeth, lobes, etc.).

fossilized6s Posted January 30, 2015 Share Posted January 30, 2015 Thanks paleoflor, i think you nailed it. My specimen is a Sphenophyllum emarginatum ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
