Not now and probably not when they were alive! A lot of animals do get hiccups but only if they have a diaphragm. Croccodiles, birds and reptiles don’t have a diaphragm and can’t hiccup and dinosaurs didn’t have a diaphragm either, but squirrels, cats, horses.. can! Apparently a hiccup is caused by a sudden contraction of the diaphragm which pushes air upwards abruptly.
