Nicolia is a genus of fossilized wood from the Late Cretaceous to Pleistocene of Belgium,[2] Ethiopia, Egypt, New Caledonia,[3] New Zealand, and Tunisia.[1] The type species is N. aegyptiaca.[1][4]

Discovery and naming
editThe type species Nicolia aegyptiaca were named in 1842 by Franz Unger.[5] The first specimens were collected in Egypt and it is often synonymised with Sterculioxylon aegypticum.[6]
The discovery of N. caledonica suggests the genus existed until the Pleistocene.[3]
Aachenosaurus
editIndependently in 1887, the name Aachenosaurus was created by the scientist (and abbé) Gerard Smets based on fossilized fragments found in the Aachen Formation of Moresnet (which was a neutral territory between Belgium and Germany).[2] Smets considered that the specimen was a hadrosaur reaching an estimated 4 to 5 meters in length which might have had dermal spines.[2] He defended this conclusion, citing that the fossils had been examined visually with the naked eye, magnifying lenses and with the microscope. However, his error was soon demonstrated by Louis Dollo. Smets at first tried to defend his original identification but was again proven wrong by a neutral commission.
Aachenosaurus has since been considered to be a synonym of Nicolia moresneti.[1]
A synonym of Aachenosaurus is Aachenoxylon, which was coined by Dr Maurice Hovelacque in 1889/1890.[7][8][9]
