Cover: Cretaceous terrestrial strata from the Dawson Creek section of Big Bend National Park. Outcropping in the foreground are paleosols and sandstone channels of the Javelina Formation which documents two rapid, greenhouse events and contains a dinosaur fauna that supports the hypothesis of dinosaur endemism and provinciality in North America. See “Revised age constraints for Late Cretaceous to early Paleocene terrestrial strata from the Dawson Creek section, Big Bend National Park, west Texas” by Leslie et al., p. 1143–1163.
