OUR SERVICES

The diverse branches of micropaleontology allows  us to reconstruct the paleoecological history of human occupation in archaeological sites. That is what Terra Nostra does best and offers you for your geoarchaeological research.

The biostratigraphic distribution of the great variety of microfossils in ancient and modern lakes offers a unique opportunity to identify the species and their significance by strata. Micropaleontological analysis is a powerful tool and a specialty of Terra Nostra.

Terra Nostra’s field of expertise in micropaleontological analysis allows us to identify some key species that determine the age and environment of settlement in the recent and distant past. We focus on the Pleistocene/Holocene fossil record using ostracodes, diatoms, mollusks, and other microorganisms.

At Terra Nostra, we use stable isotopes (SI) and trace elements (TE) to identify the paleoclimatic signature recorded in the organism’s shell chemical composition. We incorporate the analysis of SI and TE into the original micropaleontological studies to refine the paleoenvironmental signatures left by these organisms in the geological record.

A fundamental part of the investigations carried out by Terra Nostra includes the sedimentological analysis of the materials studied. The sediments provide the basis for understanding the settlement, development, and final burial of the different species of microscopic organisms. We offer this analysis to help our clients reconstruct the aquatic systems associated with their archaeological or natural sites.

Terra Nostra offers a detailed analysis of the paleoclimatological signatures left by the diverse group of microfossils found in the sediments of irrigation canals, reservoirs, and lakes (natural and artificial).
