A geomorphological characterization of the Tazones' Lighthouse surroundings has been carried out in order to analyze its incidence in the evolution of a section of The Dinosaur Coast and in the paleontological heritage. Fieldwork and photointerpretation have been performed to elaborate a geomorphological map of a 1.13 km2 area that includes marine, gravity and fluvial forms. In addition, the analysis of the historical evolution of the environment by means of aerial photographs and orthophotographs available since 1984, have been carried out. The presence of cracks and escarps since 1984 has revealed the instability of the area. The gravity processes have facilitated the discovery and recovery of up to 32 Jurassic vertebrate fossils along the Tazones Lighthouse Tracksite, although there is also evidence of losses of fossil heritage due to the negative repercussion of this kind of phenomena.
