Reposed the limbs of my Spinosaurus aegyptiacus skeletal reconstruction to be more in line with my new standards for my skeletal reconstructions, and finally decided to give it the raised neck posture inferred from Sigilmassasaurus.

are you planning on doing GDI estimates for your Giganotosaurus?

A complete rework of my Yangchuanosaurus shangyouensis skeletal reconstructions + some added details to the skulls and remake of CV00216's skull reconstruction. And yes, the odd dachshund-like Yangchuanosaurus was a cross-scaling mistake, although CV00216 was still proportionally shorter-legged than the holotype.

Made some new Carcharodontosaurus saharicus skull reconstructions.

Holotype specimen IPHG 1922



Neotype specimen SGM-Din 1


Filled in with Tyrannotitan quadratojugal and dentary, Shaochilong quadrate, and Acrocanthosaurus premaxilla, squamosal, and back part of the mandible. I also used Scott Hartman's Giganotosaurus skull as a basic guide to better place the elements together. Estimated skull lengths are ~1.35 meters for IPHG 1922 and ~1.61 meters for SGM-Din 1.

how did it get this long?

seems longer than an-Acro based version.
Tyrannotitan quadratojugal seems a bit small compared to Franoy's T.titan.

The Acrocanthosaurus-based premaxilla is scaled based on maxilla length.

Tyrannotitan chubutensis skull reconstructions:

Reconstructed based on Carcharodontosaurus (general proportions), Giganotosaurus (maxilla depth, lacrimal, postorbital, and quadrate), Mapusaurus (nasal), and Acrocanthosaurus (premaxilla, squamosal, back portion of mandible). Estimated skull lengths are ~1.46 meters for MPEF-PV 1156 and ~1.568 meters for MPEF-PV 1157.

Here's some whole new Carcharodontosaurus saharicus skeletal reconstructions. The previous version from back in 2015 was produced under the idea that Carcharodontosaurus was proportioned more like Acrocanthosaurus, which, as I found later on, isn't the best option really. The skull of the previous IPHG 1922 reconstruction was also restored incorrectly and far too small. This one now primarily bases on Tyrannotitan and Giganotosaurus, with some Shaochilong, Mapusaurus, and Acrocanthosaurus because you really can't avoid using Acrocanthosaurus when reconstructing any of the giant carcharodontosaurines.

Updates to my Amphicoelias skeletal reconstructions.

Amphicoelias altus AMNH 5764


Amphicoelias fragillimus AMNH 5777


Revised the limbs and girdles based on extra data I received about Tornieria, fixed the pubis articulation, revised the dorsal neural arches based on Diplodocus carnegii (which fits in better with the A. altus dorsal neural arch), and removed the assigned ulna. The changes and fixes to the limbs and girdles tilted up the dorsal column as an effect, but height still decreased overall due to the shorter limbs.

I also added the distal femur mentioned in Cope's field notes to the A. fragillimus skeletal (in light gray).

Updated the Dreadnoughtus skeletal, again.

Added the maxilla fragment, detailed the skull, tweaked the dorsal column neural arches to be more Futalognkosaurus-like, fixed neural arch articulation issues, and lowered the angle of the axial column so the distal tip of the scapula articulates properly with the approximate elevation of the dorsal diapophyses.

An Argentinosaurus huinculensis skeletal reconstruction. For an animal as popular as it is, and known from more material than enigmatic giants like Puertasaurus reuili and Amphicoelias fragillimus, it sure was harder to reconstruct than they were.

The dorsals are based on the arrangement proposed by Powell & Salgado (2010), albeit with the anterior dorsal moved one position forward due to issues with neural spine articulation. Neck allometry from Parrish & Michael (2006) applied as the isometrically-scaled version was too short to make sense ecologically on an animal of this size, an issue which plagues Carpenter's 2006 megasaltasaur Argentinosaurus reconstruction.
