The dinocephalian synapsid,
Moschops (Fig. 1), looks like it could not bend its neck down to take a drink of water from the shoreline, giraffe-style.
But Moschops could wade
into chin-deep water, maybe where it’s plant diet sprouted. Okay, no big deal, but I’ve wondered this and the simplest answer did not come to me for some time, probably because I was giraffe- and wildebeest-biased. Watching my dog walk knee deep into a pond cleared the air for me.
