Dinosaur faunas of the Judithian age may represent the peak of dinosaur evolution in North America. [8] Hadrosaurs were universally the dominant herbivore of the period and comprised more than half of "a typical assemblage." [8] This was also the period of greatest generic diversity among large herbivorous dinosaurs. [8]

Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
Scientists have unearthed nearly 200 dinosaur footprints, dating back 166 million years to the Middle Jurassic Period, at Dewars Farm Quarry in Oxfordshire, England.
Paleontology (/ ˌ p eɪ l i ɒ n ˈ t ɒ l ə dʒ i, ˌ p æ l i-,-ən-/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -ən-), also spelled palaeontology [a] or palæontology, is the scientific study of life that existed prior to the start of the Holocene epoch (roughly 11,700 years before present).
Earliest dinosaurs (prosauropods), first cardiid bivalves, diversity in cycads, bennettitaleans, and conifers. First teleost fishes. First mammals (Adelobasileus). 220 Ma Seed-producing Gymnosperm forests dominate the land; herbivores grow to huge sizes to accommodate the large guts necessary to digest the nutrient-poor plants.
1858 — The first dinosaur skeleton found in the United States, Hadrosaurus, is excavated and described by Joseph Leidy. 1859 — Charles Darwin publishes On the Origin of Species. 1861 — The first Archaeopteryx, skeleton is found in Bavaria, Germany, and recognized as a transitional form between reptiles and birds.
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 ...
