D e s c r i p t i o n. Four specimens show relatively large pinnate leaves up to 300 mm in length, with several preserved leaflets on both sides of rachis. Leaflets are rectangular in shape, usually two times longer than wide. Simple veins run parallel with leaflet margins to the apex (Pl. 4, Fig. 2b). Apical parts of leaflets are incompletely preserved. Specimen NM-F2521 (Pl. 4, Fig. 2a) is 215 mm long, with 13 preserved fragments of leaflets on one side of the 5 mm wide rachis. Sub-opposite rectangular leaflets are 12–18 mm long, 11–12 mm wide, with parallel margins, not narrowing to the base. Partly preserved apices are truncate. Distance between leaflets is 3–5 mm. Specimen no. GBA _128 (Pl. 4, Fig. 1) is an 80 mm long and represents a fragment of pinnate leaf, with five preserved rectangular leaflets on one side of 5 mm wide rachis. Leaflets are 16–17 mm long, 11–12 mm wide. Specimen no. GBA _127 (Pl. 3, Fig. 8) shows two leaflets, which are clearly longer than wide (24× 11 mm and 20× 11 mm), compared to specimen no. NHMW _28 (Pl. 4, Fig. 3), which has leaflets wider (up to 13 mm) and shorter (up to 8 mm) .

D i s c u s s i o n. Anomozamites is based on Anomozamites nilssonii (PHILLIPS) HARRIS , from the Jurassic of Yorkshire ( Pott and McLoughlin 2009). Anomozamites is similar to Pterophyllum , based on P. longifolium BRONGNIART (= P. filicoides (SCHLOTHEIM) ZEILLER ) described from the Carnian (Upper Triassic) of Neuewelt, Basel, Switzerland ( Pott et al. 2007), which shows veins dichotomously divided, and leaflets two times longer than wide. Harris (1932) points out that Anomozamites has leaflets as long as wide. However, specimens from the Maletín locality show leaflets 16–18 mm long, and only 11–12 mm wide. Pott and McLoughlin (2009) added in their emended diagnosis, that the length to width ratio in Anomozamites should be at most 2:1. Based on this, we assign the material studied from Maletín to the genus Anomozamites .
