base notes	base 40% up in cycle H9 (but implies added 400kyr duration of underlying zone from GTS2012 ""linear-Sr""). Duration = 21% of pre-Balearis Hauterivian (McArthur et al., 2007). GTS07 -- P. ligatus duration is 19% of duration of Hauterivian (McArthur et al, PPP07). Hauterivian tethyan ammonite zone ""Plesiospitidiscus ligatus"" is sometimes in quotes, because the index species is not a true ’P.ligatus’, but ’sed subseq. litt.’. This zone still awaits redefinition (Hoedemaeker et al., 1993).				comp notes
