A survey of Hemidactylus turcicus (Reptilia, Gekkonidae) was carried out every 3 weeks from March to November of 1997, in nocturnal transects in the city of Évora, Portugal. In this country this species is strictly nocturnal with a mean daily activity peak at 2hOO A.M (UTC).A model that correlates Activity and Temperature of the air is given. H. turcicus prefers, as microhabitat, walls (78%) and doors (16%) of low used houses. The average height in which they were found is about 3 meters.

Upper Jurassic nesting site from Paimogo (Lourinhã, Portugal) yielded the oldest dinosaur theropod embryos ever found. Numerous bones, including skull bones, from the skeleton of these embryos have been collected. The study of bones and embryos offers the possibility to learn more on the early life of theropod dinosaurs.
