Exogyra boussingaulti was a reclining bivalve of soft sediments found in the Tibú-Mercedes Formation of the Lower Cretaceous in the Municipality of San Andrés (Santander: Colombia). On the ecology of E. boussingaulti  very little is known in reproduction, dispersal or predation aspects, for this reason, it was determined the spatial distribution of this species through the calculation of three indices of dispersion from the data obtained from a grid drawn in a block of 2 m2. With this results was possible to infer that E. boussingaulti had a distribution in unconcentrated patches (Clumps) determined probably by its reproductive cycle and limited by competition for food at the intraspecific level. In the same way, this article is presented as a teaching strategy that contributes to the educational process of geological sciences students and with the solution to short questions in paleobiology.
