Triceps-atops. Building a new muscle reconstruction piece-by-piece over the Smithsonian skeleton scans, which I rearticulated from their current "being eaten by a T. rex" status.

Some quick size charts featuring some of the dinosaurs from my research thesis. Anyone want to have a guess at who's who?

An ornithischian menagerie would have felt incomplete without some plates, tanks, and all the pricky fellas in between.

I guess I can talk about this now. Mohler et al. (2021) describes a new specimen of Deinosuchus from the Menefee Formation of New Mexico. This represents one of the earliest occurrences of Deinosuchus and fleshes out our understanding of southern Laramida in the early Campanian. You can access the paper below, and you might see some cool stuff in the last figure... Mohler BF, McDonald AT, Wolfe DG.2021. First remains of the enormous alligatoroid Deinosuchus from the Upper Cretaceous Menefee Formation, New Mexico. PeerJ9:e11302https://doi.org/10.7717/peerj.11302 This after Titus et al. 2021 mentions a 70% complete juvenile Deinosuchus from the Kaiparowits Formation. Good week for Deinosuchus fans. I'm also working on an update of my skeletals, here's a preview:

Lost World Spec Challenge by Hyrotrioskjan, journal

Lost World Spec Challenge

Sep 5, 2020

#Spectember is upon us! And so the next Spec Challenge arrives! Last time we explored Skull Island, now we follow the tracks of Prof. Challenger into The Lost World. The lost world, in the book knows as Maple-White Land is a large, isolated plateau, a tepui. It is suited near the three nation triangle of Brazil, Venezuela and Guyana and yes, it is home to some remarkable flora and fauna. But hold your horses! Like with Skull island you will not find here the non-avian dinosaurs you seek, Challenger was a bloody adventurer, don't trust everything you read *! However even for tepui standards the Maple-White Land has a lot of strange and archaic creatures that you might mistake for some retro dinosaurs on first sight. In case you aren't familiar with tepuis I put together a bunch of papers and photos that will show you the wonders of the flora fauna and landscape. https://www.dropbox.com/sh/idynxub2d6fdbfb/AACQyE_ksdJE5yjPMTh3pDUma?dl=0 And I found this book online that you can complete

Meet Apatorhamphus! by Rahonavis70m, journal

Meet Apatorhamphus!

Feb 25, 2020

Today is a pretty important day for me. Arguably my entire life has been leading up to this moment, ever since I first laid hands on a toy dinosaur at two years old. Today, at the grand age of 22, I have officially published my first scientific paper! And it's a (relatively) big one. It is becoming increasingly obvious that the Kem Kem beds of Albian/Cenomanian Morocco contain a far higher diversity of vertebrates than initially believed. Particularly notable is the ever-growing number of pterosaurs known from the site. First we had the coloborhynchid Siroccopteryx, then the ever-numerous azhdarchoids became prominent, with the azhdarchids A

What if there was a Walking With Dinosaurs II? by Rahonavis70m, journal

What if there was a Walking With Dinosaurs II?

Jul 31, 2019

Something we’ve all asked at some point on here is ‘what if they remade Walking With Dinosaurs?’. It’s a good question, with twenty years of improved scientific understanding and special effects, what would a new WWD look like? But I am going to ask a similar but different question. In 2016, Planet Earth II blew audiences away, with Blue Planet II following in its footsteps the following year. Frozen Planet II is also currently in production. With these spectacular sequels to classic BBC Earth documentaries, why not do one for WWD? Showcasing new and improved palaeontological findings with improved special effects, and

Introducing Hesperornithoides miessleri

Jul 10, 2019

I'm afraid my summer schedule isn't going to give me much time for DA posting, but I did want to take a moment to introduce you to a new small, winged dinosaur from the Jurassic of North America that I and my coauthors named - Hesperornithoides miessleri. If you want more information about it I also wrote up a blog post you can read here: http://www.skeletaldrawing.com/home/hesperornithoides-faq7102019 Cheers!

PSA: intermediate vs indeterminate by Corallianassa, journal

PSA: intermediate vs indeterminate

May 29, 2019

Intermediate = between two forms, e.g Suskityrannus hazelae is an intermediate tyrannosauroid in between basal tyrannosaurs and derived tyrannosaurs phylogenetically. Or, for example, the teeth of Gorgosaurus are intermediate in robusticity between derived tyrannosaurines and carcharodontosaurs. Indeterminate = not determined, e.g this toe bone of an indeterminate theropod (incertae. sedis). I see them mixed up a lot and thought oh well may as well clear it up

My Bio

Brazilian Biology Student

Interests:

Early Dinosaur Evolution, especially Carnian forms

Overall evolution of Sauropodomopha and Ornithischian, their distribution and diversity

Middle-Late Triassic faunas and their Biostratigraphy

Raw phylogenetic datasets construction, e.g. combining and/or expanding previous works

Since I’m still a undergrad student I made this gallery to post some drawing (haven't done that part in years) and discuss some of my opinion in paleontology; though most of the discussion and paper comments are being transferred to my blog (that got cancelled because things I'd like to discuss there would be too important and maybe valid a paper in the future).

Still around at DA, cause I like following some friends work, rarely will post something original maybe a journal once or twice.

Since many people still are "faving" my charts and some even using my 2017 drawings as references I think I should add a disclaimer on those, but as I am too lazy to update 100+ old posts I'll add a comment to cover em all: DISCLAIMER -> size esti

Spinodrama

13 min read

There is such a long time I don't do one of this, but here it goes... a little text on everyone favorite drama series "Spinodrma". Note this was wrote for discord, I am just adapting and posting it here because it ended up too big there. I know I should have done a better job referencing the papers quote during the text, but this took me five hours and a bit more just for formatting from Deviant Art. The Two Kem-Kem Spinosaurids This part of the journal contains a summary of the argumentation and conclusion, complemented with some personal comments, to the presence of a second spinosaurid in the Kem Kem beds. Rostra Out of the characters distinguishing the rostral morphotypes, only “ventral premaxillary profile in lateral view” is kinda good, it has decent states, but is affected by distortion. The others are not totally bad characters, however they have poorly differentiated states and are affected by the taphonomical distortion and crushing of morph-B rostrum. The nares character

Have you ever thought of remaking your cladograms and/or charts to add up-to-date information?

AndreOF-Gallery

Apr 5, 2023

I did but come to the ultimate conclusion it was just going to be a lot of headache and not something I am willingly to do now that I've graduated and have work to do. Especially since posting a cladogram is awful as almost everyone in DA has no idea how to run an actual phylogenetic analysis or detect when a work is problematic, therefore I'd be bombarded with questions/requests to change something and I've don't have the time or will to deal with this anymore.
