base notes	Duration 0.29 myr (Martinez et al., 2020). Former base of Holcodiscus caillaudianus Zone (which is now a subzone in its upper part). Zones of Lower Barremian were extensively revised (Kilian Group, 2002). In particular, the former ""H. caillaudianus"" was subdivided into 3 zones. Formerly ""Pulchellia"" compressissima. Barremian tethyan ammonite zones of ’Holcodiscus caillaudianus’ (formerly spelled ’H. callaudi’) and ’N. nicklesi’ were incorporated as subzones in a single zone ’Pulchellia compressissima’ in earlier time scales. To add to confusion, the ’H. caillaudianus’ may be subdivided into an upper ’moutoniceras’ and a lower ’compressissima’ s.z. Upper 3 zones of Early Barremian given equal durations.				comp notes
