Current fieldwork in the lowermost Albian-Cenomanian Mojado Formation (Sarten member) has produced several new invertebrate trace fossil discoveries.Reported here is third documented occurrence of Planolites isp. Washita Group at Cerro de Cristo Rey Sunland Park, New Mexico, and first record this Formation.Planolites a simple, sub-horizontal, cylindrical with fill that different than host rock.It interpreted as domichnia (dwelling trace) or fodichnia (feeding possible tracemakers.It preserved most environmental settings including marine continental, from Ediacaran to Recent.At locality associated Arthrophycus, Thalassinoides, Curvolithus, so we tentatively assign ichnoassemblage Cruziana ichnofacies.Although ichnoassemblages attributed ichnofacies have been described few meters below Mesilla Valley Formation, these differ low-diversity Formation.This change may future be used define lower contact Formationat Rey.
