Pounds. We have all of one skull of Dracorex, if I remember right we have one skulls and some skull fragments of Stygimoloch, and enough skulls of Pachycephalosaurus to count off on one hand. Pachycephalosaurus was always introduced to me as the ancient equivalent of a Bighorn Sheep (Ovis canadensis), always looking for some excuse to bang their heads together. If the ceratopsian sexual maturity rule is ancestral to Marginocephalia (specific characters pop up only after sexual maturity), then I can certainly see pachycephalosaur horns and domes forming later in life. First is that as far as I know (and please correct me if I'm wrong) there is only one complete skull of Pachycephalosaurus (see picture above), and while there are other parts of the skull and dome that are known the amount of data we have for Pachycephalosaurus is still relatively meager. Jack Horner of Montana State University showed proof, from study of the skull of the one existing Dracorex specimen, that this dinosaur may well be a young form of Stygimoloch.

Along with the Dracorex, which is often … There is another issue at stake here that may very well shape some of the arguments; did dinosaurs experience high diversity in the end Cretaceous or was their diversity dwindling prior to extinction? The adult head bones could not adequately have withstood pressure and impact and the skulls lacked proper shock absorption like Big Horned Sheep, and it's more likely that they head-butted their sides, to try to knock them off balance. Roads To Moscow Chords, Two other genus, Stygimoloch and Dracorex, have recently been theorised to be juvenile specimens of Pachycephalosaurus and represent different growth stages. Cbn Flower For Sale, Some of the readers here have noted that the reabsorption/redistribution of bone has been noted in the skulls of ceratopsid dinosaurs, so if pachycephalosaurs did as well I would have to wonder if the trait was basal to the marginocephalia. Stuart the Stygimoloch. "Dinosaur Distribution". The original Ankylosaurus model.. Pachycephalosaurus, the delicately built, 15-foot-long, dome-headed dinosaur that lived alongside Tyrannosaurus and Triceratops, is a staple of children’s books and … Its snout and skull are covered by small knobs, but don't worry: Pachycephalosaurus only eats fruit and seeds.

It is famous for having a large, bony dome atop its skull, up to 25 centimeters (10 inches) thick, which safely cushioned its brain. (Of course, this could once again be due to lack of fossils.). Likewise, those who favor diversity might be more likely to favor the animals as separate, and even though such broader trends should be supported or refuted by the available evidence I won't be as naive to think that it plays some role in this issue. Thanks to Dinosaur Train, Des was introduced to the Stygimoloch first. This idea was backed up at the 2007 annual meeting of the Society of Vertebrate Paleontology. Pachycephalosaurus was added to The Isle in Patch 0.1.1.1531.

Likewise, I don't think lumping these dinosaurs together would drastically change our idea of the already spotty late Cretaceous, but I think ideas about whether dino diversity was high or low could possibly color certain leanings.

It would not surprise me at all if Dracorex, at the very least, turned out to be a juvenile Pachycephalosaurus and/or Stygimoloch. [18], Pachycephalosaurus is the most famous member of the Pachycephalosauria (though not the best-preserved member). Pachyrhinosaurus and Achuelosaurus' huge bony bosses are reabsorbed and reworked horn cores. T1 Esports Careers, Indeed, Pachycephalosarus seems to be the genus that defines how this group is seen, but there is a wider variety of pachycephalosaurs with flatter skulls like Dracorex and Stegoceras in North America and Homalocephale in Asia. Cobalt R7 Top Speed, Besides, in JW, there was a Pachycephalosaurus seen in a video camera. CrashBash 20:01, January 21, 2018 (UTC) I know there's no confirmation of Pachycephalosaurus, but I'm hopeful for it to appear, alongside Stygimoloch (if these two are different things). ).

Of course there's nothing wrong with this per se, and perhaps it's just a corrective to rampant "laissez-fair" lumping that has taken place in the past, but I do wonder how much of this resistence/enthusiasm stems from a desire to have as many cool dino species as possible. Dr. Robert Bakker is one of the most famous paleontologists working today, an iconoclastic figure who has played a leading role of rehabilitating our understanding of dinosaurs from the inception of the "Dinosaur Renaissance" through the present.

Likewise, Stygimoloch and Dracorex may show some juvenile characters or reabsorption of bone (presumably, under the hypothesis, to be redistributed in a more prominent dome), but this does not mean that they are juvenile Pachycephalosaurus. Put it all together and the most I can really say is "More fossils, please," although if I'm to be honest I'm somewhat skeptical of the new hypothesis. You're also right about the trend to erect new taxa and resistance to lumping them, although an ontogenic series would be much more interesting than a handful of fragmentary adults of hard-to-discern relation.
