Relatively diverse trace fossils made by insects, other arthropods and oligochaete worms occur in the Miocene lacustrine marginal deposits of Calatayud-Teruel basin (NE Spain). They include ichnospecies Celliforma isp., Celliforma? isp. A B, aff. habari, Rosellichnus cf. arabicus, Spongeliomorpha Labyrintichnus terrerensis n. igen. et Taenidium barreti, Beaconites filiformis Polykladichnus arag...

Trace fossils of insect feeding have contributed substantially to our understanding of the evolution of insect-plant interactions. The most complex phenotypes of herbivory are galls, whose diagnostic morphologies often allow the identification of the gall inducer. Although fossil insect-induced galls over 300Myr old are known, most are two-dimensional impressions lacking adequate morphological ...
