摘要：To example of the other basins Brazilian cretaceous, the Basin of Tacutu possesses few continental fossils registered already, however, compared to the others, she is still very little known in geological and paleontological terms, what hinders the understanding of his evolution. This situation comes gradually being changed through the recent surface researches done in the area of the basin that has been revealing important information of geological and paleontological stamp. Among the new done paleontological discoveries, they stand out the fossil logs here. These fossils are being studied with intention of elucidating aspects paleoenvironmental and paleoclimatological of the area during Mesozoic. The research still meets in preliminary phase, however, the abundance with that you/they happen allows to verify a great macroscopic morphologic variety of these logs, as well as his/her preservation state relatively good. Although unfinished, preliminary surveys indicate that this macroscopic diversity is accompanied by a similar anatomical diversity, what suggests a taxonomic diversity equally considerable to the area. Like this, the Basin of Tacutu revealed the stonemason very important fossiliferous and that can be an big tool goes the understanding of the geological evolution of the area.
