Holotype of Araripestrobus resinosus gen. nov et sp. nov. (MB.Pb.1997/1246) from the Crato Formation with in situ pollen and amber present. a Apically compressed detached cone portion with central axis (dark central oval) and the remains of microsporophylls (arrowheads). b Variously coloured amber pieces embedded within the darker brown plant tissue remains at the margin of the portion, amber clearly in rows (arrowheads) indicating the position of resin canals. c Resin canals infilled with fossil resin within the plant tissue remains showing that the densely packed canals run from the microsporophyll margin towards their interior (3 stacked images). d–f Microsporophylls with amber and various outlines (e 9 stacked images, f 5 stacked images)
