Heat Flow in the Cretaceous of Northwestern Kansas and Implications for Regional Hydrology
Temperature logs are interpreted to investigate the thermal structure of the units overlying the Kansas portion of the Cretaceous Dakota aquifer. The aim of this study is to determine if additional heat input by fluids exists and thus clarify whether the overall conductive heat flow from the basement through the sequence might be overprinted by heat advection. Although interval thermal gradient...

Reexamination of the type material of Squilla? kiowana Scott, 1970 and study of additional specimens of the same taxon indicates that it is a mecochirid decapod referable to a new genus, Huhatanka. This assignment brings to five the number of North American species referable to the Mecochiridae.
متن کاملExtreme Morphogenesis and Ecological Specialization among Cretaceous Basal Ants
Ants comprise one lineage of the triumvirate of eusocial insects and experienced their early diversification within the Cretaceous [1-9]. Their ecological success is generally attributed to their remarkable social behavior. Not all ants cooperate in social hunting, however, and some of the most effective predatory ants are solitary hunters with powerful trap jaws [10]. Recent evolutionary studi...
متن کاملMating and aggregative behaviors among basal hexapods in the Early Cretaceous
Among the many challenges in paleobiology is the inference and reconstruction of behaviors that rarely, if ever, leave a physical trace on the environment that is suitable for fossilization. Of particular significance are those behaviors tied to mating and courtship, individual interactions critical for species integrity and continuance, as well as those for dispersal, permitting the taxon to e...
