Fun stuff from the DML…
A number of recent news items:
Last night (3-7-2014) Paul Sereno gave a talk in Seattle that included
images of a reconstructed skeleton (along with animation) for a
"digging raptor" from the Sahara that is yet to be officially named or
described. He characterized the theropod as a cross between a rhea and
a wolverine--with very long hind legs but short robust forelimbs,
braced with a powerful sternum and shoulder area. The animation showed
it digging into a small mammal burrow with its long back legs crouched
flat. This combination looks similar to the one found in
alvarezsaurids--a lightly built running body with long legs, and very
short forelimbs. However, the digging raptor has three large flat
digits on its hand rather than a single massive claw. Apparently this
dinosaur had been briefly mentioned before as far back as 2012. He
implied that it will be out soon. I'm not aware of any online material
or links.
Senero hinted that much new Spinosaurus material is about to be
announced as well. It will change some details of how Spinosaurus has
been reconstructed and will make it the biggest known theropod.
So, digging Noasaurids and a new look on a giant Spinosaurus are close at hand! Bring it on baby!

Does this mean we soon will get some first information on the new Spinosaurus material I am waiting for since more than 1.5 years?

A new Torvosaurus and Edmarka scale comparison, done by the EoFauna research team. fav.me/d7anuh1Looks like they got both T. tanneri and T. gurneyi at equal sizes. |

Regarding skull length, that's consistent with Hartman's T. gurneyi and close to what I had estimated for the dry mesa adults based on Hartman's skeletal but it looks like they gave it a proportionally smaller head than Hartman (pushing up the size of T. gurneyi and T. tanneri) and that Edmarka pubis is absent in recent hypodigms.

Utahraptor silhouette(with integument) by Scott Hartman released! It turns out much stockier, bulkier, and with a build closer to multi-tonne theropods than to other dromaeosaurs. Also the downturned jaw and the procumbent teeth, something like Masiakasaurus but to a much lesser degree. phylopic.org/image/b5ba185e-61ad-40fd-a494-d4ab4e5ae1f8/Looking forward to the release of the full skeletal reconstruction.. |

I was aware from a private discussion about new material that Utahraptor will appear bulkier than usually depicted. |

I think this further supports RaptorX863's theory of raptors (at least the larger ones) morphologically resembling large big cats/or bears (rather than small, swift predators) more than thought. Not really surprising, but the small and agile hunter thing still seems to be widely believed, even in genera like Deinonychus or even Utahraptor.

Excellent. A dinosaurian sabertooth. Awesome.

Dont forget the contour feathers make it look bulkier than it is.
That being said, Utahraptor has a fairly robust body in lateral view, but I´m not sure about dorsal view. That dromaeosaurs seem so lightly built is largely because their tails, necks and snouts are so long.

So I have to be a good little boy and wait quietly for: A giant Kenyan Abelisaurid, new huge Spinosaurus material, Deinocheirus, and Utahraptor!?! My little heart can hardly take it!  |

And Sereno certified that Spinosaurus material will revise its physical description and definitely make it the largest known theropod ? |

I’ve tried measuring the volume of the Torvosaurus-model available here: julio-lacerda.deviantart.com/art/3D-Model-Contest-Torvosaurus-349622685I approximated the axial lenght by modeling a polygon edge along its curvature, but it’s not very exact. I came up with a volume of 2865l for a Torvosaurus 10m in axial lenght. Considering its phylogeny, I’d assume Torvosaurus was not very pneumatic, and a fairly high density between 0.9 and 1.0 should do. Does that sound realistic? However I’m neither sure how reliable the model is, nor am I totally confident in my measuring-addon. |
