Deinotherium giganteum
Deinotherium ("terrible beast" derived from the Ancient Greek δεινός, deinos meaning "terrible" and θηρίον, therion meaning "beast") was a large prehistoric relative of modern-day elephants that appeared in the Middle Miocene and survived until the Early Pleistocene. Deinotherium was a large proboscidean. Two adults of D. giganteum are around 3.63–4 metres (11.9–13.1 ft) tall and weighed 8.8–12 tonnes (8.7–11.8 long tons; 9.7–13.2 short tons). This is similar to adult males of D. proavum, one of which weighed 10.3 tonnes (10.1 long tons; 11.4 short tons) and was 3.59 metres (11.8 ft) tall. However, both these species are smaller than a 45-year-old male of D. "thraceiensis", at 4.01 metres (13.2 ft) tall and 13.2 tonnes (13.0 long tons; 14.6 short tons). Deinotherium's range covered parts of Asia, Africa, and Europe. Adrienne Mayor, in The First Fossil Hunters: Paleontology In Greek and Roman Times, has suggested that deinothere fossils found in Greece helped generate myths of archaic giant beings. A tooth of a deinothere found on the island of Crete, in shallow marine sediments of the Miocene suggests that Crete was closer or connected to the mainland during the Messinian salinity crisis.
Eotriceratops xerinsularis
Eotriceratops (meaning "dawn three-horned face") is a genus of herbivorous ceratopsian dinosaurs which lived in the area of North America during the late Cretaceous period. The only named species is Eotriceratops xerinsularis. Eotriceratops was named and described by Xiao-Chun Wu, Donald B. Brinkman, David A. Eberth and Dennis R. Braman in 2007. The type species is Eotriceratops xerinsularis. The generic name combines a Greek ἠώς, èos, "dawn", with the name of the genus Triceratops, in reference to an older age relative to that form. The specific name xerinsularis, means "of the dry island", from Greek ξηρός, xèros, "dry", and Latin insula, "island" and is a reference to the Dry Island Buffalo Jump Provincial Park where its remains were found. The holotype specimen, RTMP 2002.57.5, has been found in a layer of the uppermost Horseshoe Canyon Formation, dated to the early Maastrichtian, about 67.6 million years ago. It consists of a partial skeleton with skull, lacking the lower jaws. It contains a partial skull including parts of the frill sides, large horns above the eyes, and a small horn above the nose, similar to the closely related Triceratops. Its skull is said to have been around three metres long. This would put its full size estimates to 12 meters, though a more conservative estimate places the length of Eotriceratops at 9 meters (30 ft). In 2010, Paul estimated its length at 8.5 metres, its weight at ten tonnes. Eotriceratops was in 2007 placed in the Chasmosaurinae. In a cladistic analysis, it was recovered as a close relative of Triceratops, Nedoceratops and Torosaurus. It would have been the sister species of Triceratops. In view of its greater age, the describing authors considered it more likely that Eotriceratops was in fact basal to, lower in the evolutionary tree than, the other three genera.
