[eng] Palaeontological characteristics features and taxonomical affinities of ichthyological fossil are given. Stratigraphical characteristics of the deposits where it is settled are analysed. Also we analyse other variables - temperature, batimetry, substract, salinity and trophical systems -which may allow a palaeoecological approach to the environments whcre the deposits which may be attributed to the middle-upper Pliocene were formed.
