Applications of strontium concentrations and isotopes preserved in vertebrate enamel and enamel-like tissues to paleoecology studies of Silurian conodonts from Gotland, Sweden, and Cretaceous Dinosaurs and Plesiosaurs from Alberta, Canada

Strontium isotope analysis of dinosaur enamel from Dinosaur Provincial Park, Canada, reveals distinct migratory patterns: hadrosaurs traveled under 100 km, while ceratopsians ranged up to 200 km. This geochemical approach, leveraging enamel's resistance to diagenesis, also suggests some plesiosaurs inhabited freshwater environments. Additionally, conodonts from Silurian deposits in Gotland, Sweden, were found to exclusively occupy marine settings, with trophic partitioning evident among co-occurring taxa. The study highlights the potential of strontium ratios in reconstructing paleoecological behaviors and habitat preferences across evolutionary timescales.
