    I define here my own use of the term "Ka": Wikipedia defines it as "Kilo-annum", i.e. a synonymous for "Kyr" many other authors do use. I prefer the significance "Kiloyears ago" i.e. a substitute of "Kyr BP". Why do I give it such a wording? I've read "Ka" declined in several ways, and often with ambiguity, by single authors (also by myself), so have seen the opportunity to unambigously use an existing unit to render the term "Kyr BP" in a compact and known way. In the plots of this post I use always the label: "Age (Ka=Kyr BP)" in order to avoid misunderstanding.
    As a little example of such an uncertainty, the above quoted papers use: Carolin et al, 2019, Ka; Incarbona et al, 2011, kyr BP; Kawahata, 2019, Ka in the title and both yr BP and ka in figures and text; Margaritelli et al, 2020, yr BP; Mariani et al, 2018 (I'm an author, here), kyrs BP and, in one case, ka BP; Wang et al, 2005, yr BP.
    I'm not alone in this approach: e.g. Fischer(1982), well before the born of Wikipedia, wrote: "The times of these first-order glaciations (Figure 9.3) are Late Precambrian [about 750–650 m.y. ago (Ma)]," also if two almost contemporary collegues, Raup e Sepkoski (1984), outline: Abbreviation: ma, million year(s).
    The Wikipedia item Cretaceous writes: "The Cretaceous ( /krɪˈteɪ.ʃəs/, krih-TAY-shəs)[1] is a geological period that lasted from about 145 to 66 million years ago (mya).
