    Crocodilians are special.
    They have a unique heart as I remember it can work in
    3 or 4 chamber mode.
    I haven't tried for a long time but, the last time I did,
    it was difficult to find anything about their unique biology.
    Not your normal reptile.

    If we grasped the variations in the biology of what are
    lumped together as reptiles, we might find a pattern
    that might be a sort of dinosaur.

    This review of "bird brain"
    might remind us a cc of bird brain is not the same as a cc of mammalian.
    And what about all them reptilian sorts.

    First, stop thinking Mammalcentric.
    Maybe "their" brain organization has advantages.
    For them anyways.

    Don't link stuff behind paywalls please.

    NYTs is the worse.

    Dear Spooky DEAR :blowkiss:

    I get into that NYT link in #1 upload just fine.
    And I do not pay them nothin'.
    Could be your receiver, y'think?

    :)


    Above message finally figured out after taking the
    hurt :sniff: of the bird brained upload above.
    That's why it took days.
    Don't worry about Moi :sniff:
    I thought it was an illuminating upload.

    Are crocodilian brains more similar to a bird than a lizard?
    How similar is a lizard's brain to a bird vs a mammal?
    And how might that all translate to the Not A Mammal, Dinosaur.
    It's like Apple and Microsoft just didn't have different programming
    but different, competitive processor systems, & hardware too. What an epiphany plus! :eekeyes:

    That was an interesting article. Ankles huh? Who da thunk it?
    The density of bird neurone gives one to think.

    Yes

    Consider when discussing bird or dinosaur brains
    they are discussed with mammalian assumptions.

    How big it is? The assumption that size between reptile and mammal might be comparable,
    Well maybe their higher density and distribution of brain cells needs less volume?

    And considering their prevalence, we know so little about the crocodilian biology.

    They are NOT lizards nor birds.

    And @Spooky :blowkiss: does not care.

    how do lizard and crocodile brains compare? Neurone size and density wise?

    Don't know.
    Just worth checking out instead of the usual
    brain volume considerations as if all brains were
    comparable and structured alike.




    I wonder if brain anatomy is why the Reptilian people are always imaged as mean. :hmm:

    I hope you feel better for getting that off your chest? :roflol:

    I hope you feel better after posting another senseless anti-science article that clearly displays your "Amazing" intellect in play.

    Purposeful ignorance can certainly be considered "Dumb" but there are more apt terms that can be used.

    "Their results suggest that dinosaur DNA was probably organised into many chunks - called chromosomes. Birds usually have about 80 chromosomes - about three times the number humans possess. It is notable that birds are among the most varied animal groups on Earth. If, as Prof Griffin thinks, dinosaurs also had a large number of chromosomes it might explain why they too came in such a range of shapes and sizes."

    Very cool.. Thanks.

    You have to add the cerebellum to mammals. Primary agenesis of the cerebellum causes developmental delays among many other problems. There are more neurons in the cerebellum than cerebrum.
