James Ross Island was charted in October 1903 by the Swedish Antarctic Expedition (SwedAE) under Otto Nordenskiöld, who named it for Sir James Clark Ross, the leader of a British expedition to this area in 1842 that discovered and roughly charted a number of points along the eastern side of the island.

The first dinosaur discovered in Antarctica was Antarctopelta oliveroi, a medium-sized ankylosaur found on James Ross Island by Argentinian geologists Eduardo Olivero and Roberto Scasso in 1986.

[4] In December 2003, U.S. paleontologist Judd Case from Saint Mary's College of California and U.S. geologist James Martin from the South Dakota School of Mines & Technology discovered the bones of a theropod dinosaur on the island.

[5] An ornithopod was found in the Snow Hill Island Formation by Argentine paleontologists Rodolfo Aníbal Coria and Juan José Moly in 2008.

The genus name refers to the site of El Morro on James Ross Island, where the remains of the species were found.

Named by the UK Antarctic Place-Names Committee (UK-APC) in 1987 after William R. Flett, geologist on Operation Tabarin at Deception Island (Base Leader), 1943–44, and Hope Bay, 1944–45.

Cliffs located east-northeast of Stark Point, running east–west for 2 nautical miles (3.7 km; 2.3 mi) and rising to 550 metres (1,800 ft) high in northern James Ross Island.

Named by the UK-APC in 1987 after Reinhard Förster (1935–87), West German geologist from the University of Munich, who was a member of the British Antarctic Survey (BAS) field party to the area, 1985–86.

A low ice-covered point on the northeast coast of James Ross Island, 5 nautical miles (9.3 km; 5.8 mi) northwest of Cape Gage.

A rocky promontory forming the east extremity of James Ross Island and the west side of the north entrance to Admiralty Sound.

Discovered by a British expedition 1839–43, under James Clark Ross, who named it for V. Admiral William Hall Gage, a Lord Commissioner of the Admiralty.

A rocky point 4 nautical miles (7.4 km; 4.6 mi) southeast of Cape Broms, on the southwest side of James Ross Island.

A cape lying 2 nautical miles (3.7 km; 2.3 mi) southeast of Carlsson Bay on the south side of James Ross Island.

A prominent round hill 860 metres (2,820 ft) high with distinctive convex slopes, 2 nautical miles (3.7 km; 2.3 mi) inland between Cape Foster and Jefford Point.

A point formed by a rock cliff surmounted by ice, located 8 nautical miles (15 km; 9.2 mi) east-northeast of Cape Foster.

A ridge, 3 kilometres (1.9 mi) long, trending north-northwest – south-southeast, midway between Jefford Point and Tortoise Hill, southeast James Ross Island.

A hill more than 500 metres (1,600 ft) high, 3 nautical miles (5.6 km; 3.5 mi) west of The Watchtower at the southeast corner of James Ross Island.

The feature is similar geologically and in appearance to Terrapin Hill in the northeast portion of the island; hence the application of a related name.

An isolated, steep-sided, flat-topped rock mass, 400 metres (1,300 ft) high, on the southeast extremity of James Ross Island.
