• Resumen

  • A revision of the calcarenitic fossiliferous deposits in FJorth Lanzaror.c, including a new locality (Fuente Gusa), with the same characteristics, has been done. The eggs fragments of Orzola have been considered till the present as belonging to two different types of Ratites: Struthio and Aepyornis , aged arouna 10 millions years old (SAUER and ROTHE, 1972). Actually, and as the result of our investigations, we arrived to the conclusion that those eggs do not belong to the Rati tes , but to the Qdontopterygiformes , a group of big flying birds. This order has no present living forms and its fossils are dated as Caenozoic.

    They were marine seabirds of big size, related to actual Procellariiformes y Pelecaniformes (HARRISON and WALKER, 1976). The " last datations of the lava flows on and below the fossiliferous deposit, give an age of aproximately 5 millions years old ( IBARROLA et al., 1988)
