Alternatively, interpretation based on the fossil-bearing rocks along the Red Deer River in Alberta, Canada, supports the gradual extinction of non-avian dinosaurs; during the last 10 million years of the Cretaceous layers there, the number of dinosaur species seems to have decreased from about 45 to approximately 12. Other scientists have made ...
This list of the Paleozoic life of Alabama contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Alabama and are between 538.8 and 252.17 million years of age.
Sea turtle fossils are also commonly found in the Cretaceous rocks of Alabama and in 2018, a new species of Peritresius was named based on Alabama fossils. [11] Areas of Alabama not covered by seawater were home to subtropical forests. [1] Armored and duckbilled dinosaurs, like Lophorhothon [12] and Eotrachodon, [13] inhabited the state, as did ...
A study aiming to quantify the habitat of latest Cretaceous North American dinosaurs, based on data from fossil occurrences and climatic and environmental modelling, and evaluating its implications for inferring whether dinosaur diversity was in decline prior to the Cretaceous–Paleogene extinction event, was published by Chiarenza et al ...
Demopolis, Alabama The Demopolis Chalk is a geological formation in North America , within the U.S. states of Alabama , Mississippi , and Tennessee . The chalk was formed by pelagic sediments deposited along the eastern edge of the Mississippi embayment during the middle Campanian age of the Late Cretaceous . [ 1 ]

Washington is the latest state to have found their first dinosaur bone, it was recovered in 2012 but was not publicly identified until May 21, 2015. Some states contain rocks of the appropriate type and age to preserve dinosaur fossils, so the list of states with known dinosaur fossils is likely to increase in the future. [133] [134]
