Relating to or denoting an age in the Upper Jurassic period, lasting from about 157 to 155 million years ago.Also called Corallian
- ‘There are no Middle-Upper Callovian, Oxfordian or Kimmeridgian sequences preserved on the Jurassic carbonate platform edge in the Oman Mountains.’
- ‘The uppermost Guweyza, overlain by the Sid'r Formation, has yielded Oxfordian radiolarians in a more distal section.’
- ‘A prominent negative carbon isotope pulse lasting a few 10 years has been identified in Oxfordian sediments.’
- ‘Fluids escaping along the bounding faults at shallow levels fluidized uncemented Oxfordian sands, which were subsequently injected into the overlying Kimmeridgian strata.’
- ‘This organic-rich interval apparently has some lateral continuity outside the British Isles, although the zonal schemes are difficult to cross-correlate because of the provincial nature of Oxfordian ammonites.’
2Relating to or denoting the theory that Edward de Vere (1550–1604), Earl of Oxford, wrote the plays attributed to Shakespeare.
- ‘There is for example, no direct link to a discussion of the Oxfordian debate.’

- ‘That includes, for instance, the view of the Oxfordian group of scholars who say that de Vere, educated in the classics, well-travelled and acquainted with heartache and tragedy, is the man.’
The Oxfordian age or the system of rocks (chiefly coral-derived limestones) deposited during it.
2A supporter of the Oxfordian theory.
- ‘By some his literary capacities have been highly regarded: J. T. Looney identified him in 1920 as the author of Shakespeare's plays, and a sizeable body of ‘Oxfordians’ have since built on this claim.’
- ‘There are a high level of contention between the two factions - the Stratfordians and the Oxfordians.’
