Campanian Romance

Parasaurolophus spp. is my favourite hadrosaur. The colours are inspired by that of a gemsbok (Oryx gazella).

How is the parasaurolophus used its horn for sound resonating idea seen nowadays?

100% the leading hypothesis. we've even modeled what the sound would be like

Traditional art dump with some lambeosaurines! Lambeosaurus, Corythosaurus, Lambeosaurus (without any kind of ref for the last one lol). First is oil pastel, mostly Mungyo gallery pastels, Second two are cheap acrylic paint pens, thought the second includes some regular marker for tinting. These were fun! I think my digital painting workflow translates intuitively to opaque traditional media.

Edit: Lambeosaurines, not lambeosaurs. You get the idea.

J-Jaxartosuarus

1. Taxonomic Group: Jaxartosaurus is a genus within the Hadrosauroidea superfamily, classified under the family Hadrosauridae. It is a member of the hadrosaurid (duck-billed dinosaur) group. 2. Size and Weight: Jaxartosaurus was a relatively large dinosaur, measuring approximately 8 meters (26 feet) in length and weighing around 3 to 4 metric tons (6,600 to 8,800 pounds).

3. Time Period: This dinosaur lived during the Late Cretaceous period, roughly 85 to 70 million years ago.

4. Location: Fossils of Jaxartosaurus have been discovered in Central Asia, specifically in the region around the Jaxartes River (now the Syr Darya River) in Kazakhstan.

5. Diet: As a herbivore, Jaxartosaurus primarily fed on a variety of plants, using its specialized, broad dental batteries to grind vegetation. It likely consumed ferns, conifers, and flowering plants.

6. Distinctive Features: Jaxartosaurus had a distinctive, hollow, bony crest on its head, which is thought to have been used for vocalization and display. The crest structure is somewhat similar to other lambeosaurine hadrosaurids.

7. Head Structure: Its skull was elongated with a beak-like structure at the front for cropping plants. The teeth were organized into dental batteries that allowed for efficient processing of tough plant material. The crest likely housed an elaborate nasal passage.

8. Movement and Behavior: Jaxartosaurus was capable of both bipedal and quadrupedal movement. It likely relied on its hind legs for speed and agility, while using its forelimbs for support when feeding at lower levels.

9. Initial Discovery: The genus Jaxartosaurus was described by Anatoly Riabinin in 1937 based on fossil remains found near the Jaxartes River in Kazakhstan.

10. Social Behavior: Evidence suggests that Jaxartosaurus may have lived in herds, as is common among hadrosaurids. Herding behavior would have provided protection against predators and facilitated social interactions.

perezonyx

in the past there was a gorup of large sloths that instead of living in the trees dwelled on the ground, they lived in the american continent since the paleogene and during the neogene going extinct soon after the arrival of man, one specific mexican specimen was xibalbaonyx, who fell into a cave and probably died soon after [source]

tlapitzafrons (tlatolophus, huilacapitztli=flute/ocarina?, velafrons)

based on the mexican hadrosaurs velafrons and tlatolophus, and the huilacapitztli or prehispanic ocarinas velafrons and tlatolopus are lambeosaurine hadrosaurs discovered in different parts of mexico, both mainly known for their skull. as a relatively simple wind instrument there are records of ocarinas in prheispanic america that might have developed before or at the same time as the european and asian ones, i should mention its hard to find a proper nahuatl translation as i found examples of the word huilacapitztli refering to flutes and chichtli as a translation of ocarina but also lung, the name could also depend on the region or the meanings be mistranslated

The Dinosaur Lords - Victor Milán

Dinosaur Lords Book 1

Reread: Jul 2024

I really love the world for Dinosaur Lords. Knights with dinosaur mounts?? Incredible. Plus since this is a reread I was able to pick up on more things about the world building that I loved. Milán does write at the very beginning page that this would is not Earth and will never be Earth. I got the impression that this was a "made" world, like, terraformed and engineered. Which adds a cool element to it.

But the main cool factor is the dinosaurs! Like come on that's so fun. The whole human world just lives with them, they have common names for them, they ride them. I love it. The setting is very much based on western Europe, but like if Spain ruled the whole place. The common language is Spanish. And since the climate is tropical, the clothing is described as very minimal, which I thought was a hilarious touch. And in an even better touch, there's lots of bisexuality going around, a favourite of polytheistic cultures I feel. Which is what this culture has, a worldwide polytheistic religion, governed in a structure reminiscent of the Catholic Church. I could carry on and on about the worldbuilding, slut that I am for worldbuilding, but I figure I should speak a bit about the plot.

We have a nice "betrayed by the powers that be" figure who moves into a help defend the underdogs position. Basically our betrayed friend is a great military captain and is hired to help protect a province who has turned to pacifist, pseudo-communist ideals. The surrounding aristocrats take it as a sign to raid and pillage. Why there isn't more solidarity between fellow countrymen I have no idea. A common feature between medieval feudal lords? Or a plot device? I can't say. I know so little about the medieval period, I'm not sure what is pulled from irl examples and what isn't. Anyways it's time to build an army! Which I enjoy, there's something about the building an army from scratch thing, that tickles a similar place as learning magic at school thing. Satisfying and lovely.

Plus we get to learn more about war dinosaurs!! The main war mounts are Lambeosaurine hadrosaurs, all the big crested guys. As a hadrosaur lover (I lived and breathed a maiasaur skull for my honours thesis), this made me very happy. Hadrosaurs are cool guys. And yes truly "important" guys (see: men, straight, white, top warriors, 🙄) ride big theropod mounts. It's less fun for me. Plus I'm constantly wondering about their centre of gravity for having a rider. Like does the rider have to ride on their hips? Feels like the answer should be yes. Milán never says.

Malefica deckerti Prieto-Márquez & Wagner, 2022 (new genus and species)

(Type maxilla [bone in the upper jaw] of Malefica deckerti, from Prieto-Márquez and Wagner, 2022)

Meaning of name: Malefica = witch [in Latin, referring to its discovery at Bruja Canyon, with “Bruja” being Spanish for “witch”]; deckerti = for Frank Deckert [former superintendent of Big Bend National Park and discoverer of the original fossil]

Age: Late Cretaceous (Campanian)

Where found: Aguja Formation, Texas, U.S.A.

How much is known: A partial left maxilla (one of the bones in the upper jaw).

Notes: Malefica was a hadrosaurid (duck-billed dinosaur), but probably not a member of either of the two major lineages, the broad-billed saurolophines and the crested lambeosaurines, which together form the group Euhadrosauria. Up until the last decade, very few non-euhadrosaur hadrosaurids had been identified, but recent finds, including Malefica, have substantially added to the known diversity in this part of the hadrosaurid family tree.

Although Malefica is only known from a single incomplete bone, the maxilla has been found to be a useful element for distinguishing between different hadrosaurids, allowing the type specimen to be recognized as a probable new species.

[ashwings-woah]

👇👇👇 highland gliders ok?

females tend to have sharper and thinner crests so sounds are slightly more high pitched, a bit like whistles, while males have broader and wider crests that produce a variety of low pitched sounds

penguin anon/penguins-dragons originally came up with this idea

[iamthekaijuking]

Have you done an MH tree for herbivores yet, or were we just not paying attention?

I actually don’t think I will because the herbivore classification is just for “small” monsters that eat plants. It’s sort of a dubious class since technically the Blos wyverns and Gammoth would technically fall under that category.

But I can tell you what I think the various herbivores are!

Gastodon and Kestodon are technically brute wyverns related to Banbaro according to the canon trees, and honestly that actually makes quite a lot of sense and is pretty interesting so I agree! But I do have non-carnivorous brutes as heterodontosaurs.

As for the various mammals in the class… Burukku is pretty obviously a buffalo, and Erupe and Anteka are goats. Moofah seems to be a sheep. Mosswine is a pig. Kelbi actually feels like an Antilocaprid to me, which would make it related to giraffes. Popo I have as the closest living relatives of Gammoth, which together are descendants of early Proboscideans that split off from all other more “normal” members.

Epioth I actually covered in my recent tree!

Larinoth feels like a titanosaur of some kind, albeit an odd one. Both Slagtoth and Rhenoplos are ceratopsians, and Slagtoth in particular feels like a member of the Pachyrhinosaurini. Aptonoth seems to be a heavily armored Lambeosaurine. Apceros… I’m not so sure on. Ankylosaur is tempting but it’s shell is very different from them, so “Thyreophoran” is as much as I can narrow it down.

Gowngoat… I don’t know. It’s got this weird mish mash of dinosaur and goat traits. Maybe ornithopod??

Corythosaurus

(temporal range: 77-75.7 mio. years ago)

[text from the Wikipedia article, see also link above]

Corythosaurus (/kəˌrɪθəˈsɔːrəs/;[1] lit. 'helmeted lizard') is a genus of hadrosaurid "duck-billed" dinosaur from the Late Cretaceous period, about 77–75.7 million years ago, in what is now western North America. Its name is derived from the Greek word κόρυς, meaning "helmet", named and described in 1914 by Barnum Brown. Corythosaurus is now thought to be a lambeosaurine, thus related to Lambeosaurus, Nipponosaurus, Velafrons, Hypacrosaurus, and Olorotitan. Corythosaurus has an estimated length of 7.7–9 metres (25–30 ft) and has a skull, including the crest, that is 70.8 centimetres (27.9 in; 2.32 ft) tall.

Corythosaurus is known from many complete specimens, including the nearly complete holotype found by Brown in 1911. The holotype skeleton is only missing the last section of the tail and part of the front legs, but was preserved with impressions of polygonal scales. Corythosaurus is known from many skulls with tall crests that resemble those of the cassowary and a Corinthian helmet. The most likely function of the crest is thought to be vocalization. As in a trombone, sound waves would travel through many chambers in the crest and then get amplified when Corythosaurus exhaled. One Corythosaurus specimen has even been preserved with its last meal in its chest cavity. Inside the cavity were remains of conifer needles, seeds, twigs, and fruits, suggesting that Corythosaurus probably fed on all of these.[2]

The two species of Corythosaurus are both present in slightly different levels of the Dinosaur Park Formation. Both still co-existed with theropods and other ornithischians, like Daspletosaurus, Brachylophosaurus, Parasaurolophus, Scolosaurus, and Chasmosaurus.

[a-dinosaur-a-day]

Do we have any idea what velociraptors and pterodactyls/pterosaurs sounded like? Asking because often people will say they screeched like a velociraptor/pterodactyl when they make this high pitched shrieking sound and I'm wondering if that's in any way accurate.

Yeah we got nothing. There are quite a few dinosaurs that we know how they sounded, like Lambeosaurines, and of course living ones. But not those.

That said, we can make educated guesses based on living birds. Hisses, low rumbles, that kind of thing.
