Again sharing some results from my graphic double integration works on a few dinosaurs done using a MATLAB script which takes 1-pixel wide slices.
Note that the lengths listed in the tables are straight-line tip-to-tip lengths.
Mamenchisaurus sinocanadorum
Note: Lateral view is a Scott Hartman-ized version of Greg Paul's Mamenchisaurus sinocanadorum skeletal reconstruction. Top view based on Greg Paul's Omeisaurus tianfuensis. Overall scale is based on his megafauna size chart in the 2010 edition of Princeton Field Guide to Dinosaurs.
Recommended density: ~0.85 kg/liter
Giganotosaurus carolinii (GetAwayTrike + Scott Hartman composite reconstruction with corrected pubis)
Note: This is an alternate take on the animal. The animal's torso may very well be shorter (See the Giganotosaurus GDI on the previous GDI results sharing journal), but, without any proper description of the axial column, having no photographs, illustrations, measurement tables, or anything really, it can't really be confirmed either way.
Recommended density: ~0.915 kg/liter
Gryposaurus monumentensis
Note: Top view and limb front views based on the Bates et al. Edmontosaurus model.
Recommended density: ~1 kg/liter
Amphicoelias altus/fragillimus
Note: Top view based on Scott Hartman's Supersaurus and Greg Paul's Diplodocus. Click on the image to see the full size version in order to see the data table better.
Recommended density: ~0.85 kg/liter
Spinosaurus aegyptiacus
Note: Postcranial top view edited from Scott Hartman's Giganotosaurus modified to fit Spinosaurus, assuming a ribcage width:height ratio of roughly 1:1 as inferred from the neotype skeleton. Cranial top view based on theropod1's skull reconstruction. Click on the image to see the full size version in order to see the data table.
Recommended density: ~0.95 kg/liter
Magnapaulia laticaudus
Note: Top view and limb front views based on Greg Paul's Hypacrosaurus. Click on the image to see the full size version in order to see the data table.
Recommended density: ~1 kg/liter

Volumetric estimate for Giganotosaurus
I had performed a volumetric analysis on my Giganotosaurus carolinii reconstruction to see how voluminous and massive it might have been, well, my take on it. This also has implications for its lifestyle in regards to a certain hypothesis claiming allosauroids to be obligate scavengers...

Edwin's two-beamed sauropod
The diplodocid taxon Dystylosaurus edwini has long been commonly assumed to be a synonym of Supersaurus. But does this long-held idea still really hold up? Full blogpost: https://thesauropodomorphlair.wordpress.com/2021/05/28/edwins-two-beamed-sauropod/
Size of the duck titans
My take on size estimations for adult Edmontosaurus annectens. Some of them got real big... Full blogpost: https://thesauropodomorphlair.wordpress.com/2021/02/10/size-of-the-duck-titans/
Tetrapod body densities and updated mass estimates
Haven't gotten out a blog post in a while. Sorry for the hiatus, but it took some time to get the hang of Wordpress' block editor. Without further ado, here's the new post. New published data on tetrapod body densities, and updates to my previous mass estimations.
