theropod of the day

2-day gouache painting of Yi qi, the bizarre new membrane-winged scansoriopterygid. I wanted to see what the membrane would look like attaching further down on the body than in nearly every depiction I’ve seen so far, which show it attaching on the flank or at the armpit. I can’t get behind a leg-attachment point for this critter; it makes more sense to me that a long-legged animal would want its legs free and flexible. If a sprawling mobile hip-joint can be established for scansors, I’d potentially change my stance on that. Anyway, here’s a semi-new interpretation amidst a flood of recent restorations.

I’m definitely not convinced of powered flight for this critter, so here it is in an extended leap onto a log in pursuit of a Tiaojishan archisargid fly, Calosargus.


As I finish up my first official T.O.T.D. post, I’m realising it isn’t at all short. I have a tendency to get very excited when I talk about this stuff, so I always find it hard to shorten everything as a whole down. I can explain something (example: the growth rate of Tyrannosaurus) shortly, but I like to write about all difference aspects, facts, and other not-so-well-known information for you guys. I’m just hoping it won’t be too long where no one will want to read. Of course, every post will vary in length because there are just some theropods we do not know enough about yet.

So in the end, are you guys down for lots of information or rather keep it short and sweet? Below is a screencap of what I have (it’s not complete yet) on T. rex. Too long?

Chilesaurus diegosuarezi

Source: My friend fezraptor!

Name: Chilesaurus diegosuarezi

Name Meaning: Chile Lizard 

First Described: 2015

Described By: Novas et al. 

ClassificationDinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae

Chilesaurus is a rather sad new discovery as it was discovered only a few days before Yi qi, which overshadowed it in the media - but Chilesaurus really was robbed as it is probably one of the weirdest dinosaurs discovered this year. Why was it weird, you ask? It was a relatively advanced theropod… and an herbivore… but not a maniraptoriform. Seriously, this is weird. Its closest relatives were things like Cryolophosaurus. It lived about 145 million years ago in the Tithonian age of the Late Jurassic, and it was found in the Taqui Formation in Chile, which isn’t exactly a non-avian dinosaur rich country. It was about 3.2 meters long. It also had a backward pointing pubic bone to make room for a large gut… like Ornithischians… but it had enough features for it to be classified as not only a Saurischian, but a Theropod. Its hindlimbs were less adapted to running than its relatives, and it had strong arms with which it could defend itself, using a large first claw to do so. It had traits of Coelurosaurs, basal Sauropodomorphs, and Ornithischians… but belonged to none of those groups. What a weird little dinosaur.

Have a theropod you'd like me to write about? List it below!

I know I have to get some more TOTD posts up, but I lost the list of requests. These posts do take time to write, and I’m not on Tumblr or my Mac 24/7 to write them daily (as you guys have figured out by now haha).

But I’m going to make this the official request post. Keep your requests for theropods in the Mesozoic, please. Here’s that mandatory question mark so you can answer?

Alright, people. "Theropod Of The Day" is a GO!

Even though only about 2 or 3 three people said I should do it, I’m going to start it up anyway. I’m pretty busy right now with a lot of different things (including lots of fossil and mineral stuff, of course), but soon I’m going to start a series which will have fun facts about all types of theropods (ex: T. rex, Allosaurus, the family Dromaeosauridae, etc)!

When it gets started and you’d like to request a theropod, just hit my ask up. There needs to be more love on this site for the dinosaurs!

Fukuivenator paradoxus

By Jack Wood on @thewoodparable 

Name: Fukuivenator paradoxus

Name Meaning: Fukui Hunter 

First Described: 2016

Described By: Azuma et al. 

ClassificationDinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes

Fukuivenator was a Maniraptoriform found in the Kitadani Formation in Japan, and it’s always rare to find a dinosaur in Japan so that’s fun. It lived about 120 million years ago in the Aptian age of the Early Cretaceous. It was a unique animal in that it had a lot of primitive and advanced features for Coelurosaurs, and was placed as a basal Maniraptoriform, unable to be resolved further than that - making it similar to Ornithomimosaurs and Maniraptorans such as Therizinosaurs and Alvarezsaurs. It is known from a partial skeleton with a skull, and is the most complete non-avian dinosaur known from Japan. It had different types of teeth, some with flattened ends, which means that it may have been omnivorous rather than a pure carnivore, which would be consistent with our understanding of Avian evolution. It had a similar specialized raised second toe, like Dromaeosaurs and Troodontids, however that’s seen as an example of convergent evolution, rather than an ancestral trait.

Posts I'm currently writing up:
  • Masterlist of palaeontology group digs in western North America.
  • What to do if you find a fossil (especially a big one).
  • How to find fossils, rocks, minerals. What tools you’ll need, etc.
  • More Theropod Of The Day posts, of course!
  • Why palaeontology is important for science and society.
  • Posts on dinosaurs and technology.

I’ve got other things as well, but those are some key topics I’ll be talking about. If you have anything you’d like me to cover, let me know! Have a look through my past posts as well on: science, geology, palaeontology, paleontology (yes I use both tags), dinosaurs, & Theropod Of The Day.

Planning to have the first official T.O.T.D. post up today!

It’ll be on Tyrannosaurus rex! Thought I may as well start off with the “tyrant lizard king” before moving on to the others. I’ll be able to have about 4-5 this week, but with an event coming up in a week, things will be sporadic until that’s over.

Keep a lookout, and I’ll have it posted as soon as possibe!

Theropod Of The Day updates.

So I know many of you are patiently awaiting my T.O.T.D. series, and I can’t thank you enough for the positive feedback I’ve received on the upcoming series. Here’s a little bit of information on how the process is going/will occur:

As I’m getting the rest of the posts ready to go, I have been making mini-T.O.T.D. posts on reblogs and originals, which you can find on my Theropod Of The Day tag, giving short facts and information as a preview to what I have in store. The true/full posts will be labelled with “Theropod Of The Day” as well. Also, I cannot promise I’ll have posts every day as my schedule can be hectic, but I’ll do my best to have them as soon as possible. If there’s ever a day I cannot get a T.O.T.D. post up, there will be at least smaller reblogs/entries with a little bit of information.

Always feel free to send me a message with a theropod request! I’m planning to cover as many as possible (if not all), but if there is one you’re dying to hear about, a request will have that dinosaur farther up on the list to be posted.
