The rare earth element (REE) composition of a fossil bone reflects its chemical alteration during diagenesis. Consequently, fossils presenting low REE concentrations and/or REE profiles indicative of simple diffusion, signifying minimal alteration, h

The Standing Rock Hadrosaur Site (SRHS) in South Dakota preserves a mass-death assemblage of the hadrosaurine dinosaur Edmontosaurus annectens in the Upper Cretaceous Hell Creek Formation. A previous study of SRHS bones found many of them to yield mi

The effects of manganese (Mn) mineral mixtures on arsenite (As(III)) removal (i.e., the sum of As(III) oxidation to As(V) and As species adsorption) were systematically quantified for the first time using varying ratios of hausmannite and manganite,

Degree of bioturbation, Thalassinoides isp. morphology, and diameters were compared across the Cretaceous–Paleogene (K–Pg) boundary interval at three localities along the New Jersey coastal plain. Within this regionally extensive ichnoassemblage,
