So we have two locations at noticeably different latitude, longitude, configuration of continents and oceans, water depth, and whatnot; so how different was it? It's mightily interesting if you ask me! So I have been having a blast reading up on it. Forams! My specialism often vanishes in the more general teaching things like essay writing and the pedagogy of assessment and teaching of other things such as glaciology and evolution. But here I have a chance again to ponder forams. Such modest creatures; unicellular, and not even animals (they're protists), but still, the messengers from a time that long ago. Easy to remember why I fell for them in the first place!
