Abstract

Middle Miocene lacustrine marls from the Gracanica coal mine ~ 10 km SSE of the city of Bugojno, Bosnia and Herzegovina, have yielded a species-poor florule comprised of angiosperm leaves (Lauraceae, Myricaceae, "Rhamnus"warthae),Glyptostrobus europaeustwigs, a frond fragment ofPronephrium stiriacum, and a seed assignable to the Vitaceae. The composition of the florule is suggestive of a swampy lowland environment;climatic conditions were humid subtropical (Cfa climate). Lignite seams containing abundant fossil wood (including large logs) characterise the deposits underlying the marls;the interburden between the lignite has yielded abundant plant chaff, including shoot fragments ofEquisetum, and the charophyte gyrogonitesLychnothamnus duplicicarinatusandChara molassica notata.
