Glaciesaurus polaris

Glaciesaurus polaris was a polar member of the Dinychidae family, a group of large predatory dinosaurs. It was found in slightly higher latitudes than would be expected from it’s kind. However analysis of the many plant fossils found alongside Glaciesaurus fossils show a semi-tropical floodplain environment, indicating that the climate of the Iridaceous period was either warmer, or that a previous climate de-lateralization occurred at the time.
