Prehistoric Life/Dinosaurs/Pachycephalosaurs: Difference between revisions

* Remember ''Majungatholus'', that pachycephalosaur which revealed to be the horn of a ''giant theropod''? This was not an isolated case. ''Yaverlandia'' from Early Cretaceous England, was once mentioned as the “most ancient pachycephalosaur”, but its only remain (a tiny skull-dome with two small thickenings above) has been reclassified as a [[Science Marches On|bird-like theropod]]. Many things might deceptively resemble pachy domes and lead experts in error; the fact that pachycephalosaurs included some of the tiniest dinosaurs has also contributed to this. Still another piece of bone has been attributed to another virtually-unknown pachycephalosaur, which could get nonetheless a mention in the Guinness Book Of Records… as “the longest dinosaur name”: ''Micropachycephalosaurus'' [[hottip: *:<ref> [[Up to Eleven|It’s unlikely that someone will break this record with an even longer new dinosaur name… at least we hope]]</ref>, “tiny thick-headed lizard”. The ironical thing is, this was one of the smallest dinos that ever lived, only 50 cm/1.5 ft long. And was more likely a very primitive ceratopsian rather than a true pachycephalosaur.
