Updated biostratigraphy of Jurassic (lower Kimmeridgian) deposits containing the ammonite Ataxioceras from the eastern Iberian Range, northeastern Spain

Figures & data

Fig. 1 Location and palaeogeography of the studied sections in E–NE Spain with indication of ammonite records relevant for biostratigraphic correlation. Lithological columns show limestones, marly-limestones and marls from the Loriguilla Formation. Numbers of topographic sheets (1:50,000) for location: 467 (Muniesa), 494 (Calanda), 495 (Castelserás), 518 (Montalbán), 519 (Aguaviva), 543 (Villarluengo). Palaeogeography according to Olóriz (2000).

Fig. 3 Three species relevant for biostratigraphy and correlation of the A. lothari Biozone in the eastern Iberian Chain, ENE Spain. A. Ataxioceras lothari lothari (Oppel) [m], MPR.36.5 from the MPR section. B. G. aragoniense Moliner and Olóriz [m], MPC.28.73 from the MPC section. C. Ataxioceras hippolytense Atrops [m], MBV1.13.2 from the MBV section. White stars for the beginning of the body-chamber. All the specimens are housed in the repository of the Palaeontological collection of the University of Granada, Spain.
