    Hey Ben, it's tRICKy! One idea worthy of consideration, for the dolphin, would be to set up hydrophones to pick up whatever sounds she emits, to relay them immediately, by appropriate means, to a boat, to broadcast closest to wherever her family is most likely to be, or try several pods simultaneously, if possible, moving whichever responds to her vocalisations to her location? Leave the truck, with sling, there, for her pod to take her out of the lagoon themselves. I told you, it's tRICKy!

    Missed opportunities for headlines: Dianocodon is now the basalmost monotreme/mammal and Feredocodon is a proximal outgroup taxon, despite their Early Jurassic Age.
    The ear bone transition story has been known since the 1980s, so that's old news, made to sound new. I included that sequence in my 1991 book "From the Beginning - The Story of Human Evolution" (Wm Morrow).
    The canines on Feredocodon are not long curved cones, but short and tricuspid. That's also big overlooked news.
    Final point: the ear pinna did not develop in pre-mammals and monotremes, so the illustration is a bit off in adding them here.
    Details and links by googling, "Toothy Feredocodon enters the LRT just outside the Mammalia" and "Dianoconodon enters the LRT as the most primitive mammal".

    When I see some bone in the rat's jaw developing very successfully, I don't understand why human teeth didn't develop successfully as well? To think that dogs never have cories, because their teeth are just bone. Why do people have nerves in their teeth, why is there such a thin layer of enamel? There is a chance that human teeth will someday evolve into something better and get rid of periodontal disease and caries?

Dogs are less likely than humans to develop caries due to the very high pH of canine saliva, which prevents the formation of an acidic environment and the subsequent demineralization of the enamel that could occur.
