Plant.
Split nodule containing a positive / negative half of an usual plant. At first glance it looks like a Cordaites leaf but the outer surface and structure is completely different. Two possibilities are: 1/ Megaphyton frondosum Artis or 2/ the even rarer Ptychopteris sp. Never seen anything quite like it before. Weird.
Carboniferous, Westphalian, Coal Measures.
West Houghton near Bolton, Lancashire.
Nodule : 5.5 x 4.5 cm.
