Qianlong shouhu Han et al., 2023 (new genus and species)
Tumblr media
(Select bones and schematic skeletals of adult [a] and embryonic [b] individuals of Qianlong shouhu, with preserved bones in gray, from Han et al., 2023)
Meaning of name: Qianlong = Qian [alternative name for Guizhou] dragon [in Chinese]; shouhu = guarding [in Chinese]
Age: Early Jurassic (Sinemurian?)
Where found: Ziliujing Formation, Guizhou, China
How much is known: Three partial skeletons of adult individuals and five clutches of 3–16 eggs containing embryos.
Notes: Qianlong was an early sauropodomorph. It is notable not only for the exceptional preservation of its fossils, but also the fact that these specimens appear to be associated with nests, thus offering valuable information on their growth and reproductive behavior. As has also been found for some early sauropodomorphs, such as Massospondylus from the Early Jurassic of Southern Africa and Mussaurus from the Early Jurassic of Argentina, Qianlong appears to have laid its eggs in breeding colonies with adult individuals potentially watching over their nests. Qianlong was additionally similar to these other early sauropodomorph in being bipedal as an adult, but likely quadrupedal as a young juvenile.
Rigid, hard-shelled eggs have been found in multiple groups of dinosaurs, including tetanuran theropods (such as birds), hadrosaurids (duck-billed dinosaurs), and titanosaurian sauropods, as well as their closest living relatives, the crocodylians. As a result, it was long assumed that all dinosaurs probably laid hard-shelled eggs. However, recent evidence has suggested that the eggs of early dinosaurs may have instead had flexible, leathery shells, more similar to those of most lizards and some turtles, with rigid eggshells evolving several times in later dinosaur groups. The eggshells of Qianlong appear to have been leathery in structure, lending support to this hypothesis.

One of my monthly goals is to stitch one dinosaur on this A-Z Dinosaur Chart. As you can see they're very confetti heavy, so only doing one a month is a good amount for now so I can work on other projects at the same time but still make progress. Though I do hope I can get one of my other longish term projects done soon so I can dedicate more time to this project as I do love stitching the dinosaurs.
But with that said, this month's dino is the heterodontosaurus, a small plant eating dinosaur that was found in the 60's in South Africa from the Early Jurassic era (200-190 million years ago). Look at that little guy!

I finished this earlier this month but I was waiting until Thanksgiving to post it.  For this year's Thanksgiving piece I decided to do the dinosaurs of Massachusetts.  This was relatively easy as there were only two of them from what I could find.  The one in the front is Podokesaurus Holyokensis, a light bodied predator and the Massachusetts' official state dinosaur.  The second is Anchisaurus, a relatively small sauropodomorph (an ancestor of sauropods).  Both existed in the early Jurassic period so they would have coexisted with each other as Pokodesaurus was more built for hunting small animals rather than larger prey. Happy Thanksgiving everyone! As always, comments and critiques are welcome. P.S. I used some of thee colors found on turkeys to color Podokesaurus.

SIGHS. alright so i watched the geeked week livestream and there was no additional news/visuals for chaos theory outside what was already leaked earlier this week ;( we didn't even get a real release date, just some vague promise that it'd be "coming soon" 😭 a bit disappointing but tbf, we weren't even supposed to see the teaser trailer until today, so not their fault they didn't have anything new to show us

Just got back from the Jurassic Park (I) and Jurassic World Dominion double feature and, two non-spoiler things to note:
1. I enjoyed Dominion a shocking amount, way more than I expected. I went in with very low expectations, given how much I didn't like Fallen Kingdom, but Dominion felt very different. It felt like it paid proper homage to the original Jurassic Park movies as well as the Jurassic World movies, and felt like a satisfying end to the franchise, as much as it can be. The new characters also are amazing.
2. After watching, I absolutely GET why these two films were paired. No spoilers, but if you're planning on seeing this movie and it's been a while since you've seen the OG Jurassic Park, do yourself a favor and do a refresher watching prior to Dominion. I think you'll like Dominion a lot more if you do. (only the very first Jurassic Park movie is really necessary, though i'm sure watching the whole JP trilogy/JW trilogy may enhance your experience in ways that I missed)
Was Dominion perfect? Of course not. But I think it did a good job, had some neat ideas both old and new, juggled its massive cast excellently, and most importantly, entertained me.

Jurassic Bark ship really do be three animatronics just going absolutely insane but in different ways over two other people.
Roxy? Psh. She's not in love with Chica! Don't be ridiculous!! What she's feeling? Nah, that's not romantic. It can't be! This is just how they've always been!!! Right??? Chica's super affectionate with her!! She's just... returning the favour every now and then!! There's nothing wrong with that okay?? There's absolutely nothing else going on there!! And her and Monty?? HAH YEAH RIGHT!! She'd rather beat him into the ground than snuggle with him on the couch!! They're rivals!! They're competitors!!! It's fun competing with him and she wouldn't ever want to risk losing to anyone else!!! She'd rather be with anyone but him!! He's the only one that can match her in competition and he's always honored when she stopped it when she thought it was unfair!! He'd never cheat to beat her he's better than that!! He respects her too much and that's FINE!!! And she's TOTALLY okay with it being like this she doesn't WANT to feels his claws in her hair or to give him little bites on his arm to tell him she cares or to laugh with him until the sunrises!! She would never want that!! ......Wait no oh god oh no this can't be happening why'd it have to be BOTH of them holy fuck one was bad enough fuck shit fuck fuck fuck fuck noooooooo-
Monty and Roxy? Don't be stupid. He could NEVER be with her!! Sure, she's the only one that match him in almost any game they play but he'd rather kick her ass at the next fight night!! He doesn't wanna be all cutesy with her!! They're FIGHTERS and he's NOT INTERESTED and she's NOT FUNNY even a LITTLE BIT and they DON'T make each other SMILE don't be fucking stupid!!! He has NOT fallen for her!!! He's not being affectionate with her at all!!! He's just... making sure she knows he's got her back!!! Rivals do that ya know!! What?? NO her tail wags AREN'T cute shut the FUCK up!!! FINE OKAY THEY'RE KINDA SORTA FRIENDS NOW BUT THAT'S IT OKAY?? FUCK OFF!!! And Chica? Well Chica's one of his best friends!!! That's all he's feeling, right?? They're just super close!!! They're... like Roxy and DJ or something and it doesn't feel wrong to say that no no no absolutely not!!! He doesn't love her little chirps or think her singing little rhymes to herself as she does her own thing is cute!! He likes COOL things okay??? It MIGHT be cool that she jumps down from the ceiling to scare the staff and it MIGHT be cool that she can play the electric guitar so well and it MIGHT be cool to hang out with her sometimes but THATS IT!!! No he does NOT find all of that cute as well!!! NO NO NO NO HE'S COOL AND AWESOME AND HE'S NOT FALLING IN LOVE WITH HIS TWO BESTIES GOD DAMN IT NO NO NO FUCKING NOOOOOOOO DON'T DO THIS TO HIIIIMMMMM-
Chica? Crushing. She's crushing so hard. On two people? Yes on two people. Confusing but whatever she's over it. She's crossed that bridge already. Roxy is so cute and pretty and cool and Monty is so handsome and cute and cool... and they're both just so nice to her!! They make her laugh, she makes them laugh and oh they can smile and light up the whole world in her eyes!! And they've really come out of their shells with her!! They're so much more affectionate and they're just so cute and she loves them both so so so much!!! But... they're getting awful close to each other... no... they're not a thing! She would know if they were a thing!! They're terrible at hiding things!! They'd be way more obvious!!! And they're acting super nice to her too and well. They're CERTAINLY not a thing!! What do you mean they're acting super affectionate with her too?? No no no... that's just... how they always are!! Or is it?? But what if it is??? What if they're falling for each other and they've got no room for her anymore?? Oh but the three of them are always together so what if they do have room for her??? That was a platonic hug they just gave her right??? They're getting really big on those compliments too!! Ohhh she's not gonna explode she's fine okay it's fine they're not falling for her hahahaa she's just being silly!!! Crushes always pass right?? She'l be over it soon!! It's fine its fine its fine there's a logical explanation for ALL of this she swears she's fine she's not going to combust into flames cause Roxy made her a little sculpture out of scrap metal OR because Monty gave her a side hug and said she looked cute with his glasses on!! No no no she's soooooooooooo fine!!! What are you talking about she's SO fine she swears-

Perijasaurus lapaz Rincón et al., 2022 (new genus and species)
Tumblr media
(Part of the type vertebra of Perijasaurus lapaz, with broken regions in orange and reconstructed regions or surrounding rock in yellow, from Rincón et al., 2022)
Meaning of name: Perijasaurus = Serranía del Perijá lizard [in Greek]; lapaz = La Paz [town near where the original fossil was discovered]
Age: Early or Middle Jurassic (Toarcian or Aalenian)
Where found: La Quinta Formation, Cesar, Colombia
How much is known: A single back vertebra.
Notes: Perijasaurus was an early sauropod, known from closer to the Equator than any other Early or Middle Jurassic sauropod. The type specimen of this dinosaur had been previously described in 1955, but was left unnamed at the time. Following a reexamination of the fossil, the authors of a new study gave it a name and reinterpreted it in light of what is now known about sauropod diversity. The only known vertebra of Perijasaurus is not as extensively hollow as those of later sauropods, suggesting that it represents an intermediate stage in the evolution of weight-saving features in sauropod vertebrae.

Cesar, Colombia) and the initial diversification of eusauropods at low latitudes. Journal of Vertebrate Paleontology advance online publication. doi: 10.1080/02724634.2021.2077112

A couple more dinos.
I have been obsessing over Path of Titans,
Im gonna boldly say that I am pretty sure Yutyrannus is a favorite carnivore! But Deinocheirus is also a legend. I do like Allosaurus and concaventator too??
Anyway, these are old characters going through some 2023 love!
