These genera are recognised as having evolved from ancient lineages of the family Myrtaceae. According to genetic, fossil and morphological evidence, it is hypothesised that they evolved into separate taxa before the evolution of the more widespread and well-known genera Eucalyptus, Corymbia and Angophora, and all of their many species.

Eucalyptus (/ ˌ juː k ə ˈ l ɪ p t ə s /) [3] is a genus of more than 700 species of flowering plants in the family Myrtaceae.Most species of Eucalyptus are trees, often mallees, and a few are shrubs.
The earliest definitive Eucalyptus fossils were dated from 51.9 Ma, and were found in the Laguna del Hunco deposit in Chubut province in Argentina. [115] Cooling began mid-period, and by the end of the Eocene continental interiors had begun to dry, with forests thinning considerably in some areas.
Pimenta dioica. Myrtaceae (/ m ə r ˈ t eɪ s i ˌ aɪ,-s iː ˌ iː /), the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group.
Eucalypteae is a large tribe of flowering plants in the family Myrtaceae; members of this tribe are known as eucalypts. [1] [2] In Australia the genera Angophora, Corymbia, and Eucalyptus are commonly known as gum trees, for the sticky substance that exudes from the trunk of some species. [3]

Centurion is the name given to a single Eucalyptus regnans tree growing in Southern Tasmania, Australia, and the world's tallest known Eucalyptus.The tree was first measured by climber-deployed tapeline at 99.6 metres (327 ft) tall in 2008, and was subsequently re-measured to be 100.5 metres (330 ft) tall by ground laser in 2018.
Euoplocephalus, following the synonymizations proposed by Coombs (1971), was thought to exist for far longer, and was a member of more distinct faunas, than any of its contemporaries, as these fossils date to between 76.5 and 67 million years ago, in the Campanian-Maastrichtian ages of the late Cretaceous period, and came from the Dinosaur Park ...
