Dismissing every opponent in a series, and twin 90s in ODIs

What is the most players used by a team in a Test series such that one opposing bowler dismissed all of them? - Michael Jones

16, used by Australia in India in 2012-13 - MJ Clarke, EJM Cowan, XJ Doherty, BJ Haddin, MC Henriques, PJ Hughes, MG Johnson, NM Lyon, GJ Maxwell, JL Pattinson, PM Siddle, SPD Smith, PM Siddle, MS Wade, DA Warner and SR Watson - when R Ashwin (29 wickets in the series) dismissed all of them.

Three instances of 15 (bowlers in parentheses):

India (SP Gupte) v New Zealand in India, 1955-56
England (JH Wardle) v South Africa in South Africa, 1956-57
(Wardle played in only four matches of the 5-match series)
India (BS Chandrasekhar) v England in India, 1972-73

Note - England used 29 players during their home series against Australia in 1989; Terry Alderman dismissed 23 of them, the most different players dismissed by a bowler in any Test series.
