Description
Leptoceratops is so badass <3Female and ontogeny are in the works.
Part of the concept art I'm doing for Saurian .
WE ARE ON KICKSTARTER NOW!

Goodbye, leptoceratops... I will always remember you...

Leptoceratops will not be in the game.
👍: 0 ⏩: 1
Oh no! How come? Apparently it was in Hell Creek :/
👍: 0 ⏩: 1
not in the upper layers of Hell Creek (or Bone Butte for that matter), when Saurian is taking place.

Yeah... About that.
From this year SVP: vertpaleo.org/Annual-Meeting/A…
*Dakotaraptor holotype and paratype come from Bone Butte, which like ESPH is within Harding County, South Dakota. Meaning that Leptoceratops has been recently identified in the temporal unit and general vecinity of Bone Butte. It was there almost 100%

we don't know if it's from the exact same layers as Bone Butte, and besides, it's around 35 kilometers away from Bone Butte (red circle is ESPH area, blue square is Bone Butte).
anyways, or anyone else going to the SVP meeting would have to watch the presentation itself, and likely speak with the authors themselves.
note: posting the contents of individual abstracts on blogs or social media without the author(s')'s is banned by SVP, since that's breaking the embargo and can get you in big trouble; you'll need to wait for it to be publicly presented. links to the abstract book is fine though.

Fair enough, though if that's the case why did the authors treat East Short Pine Hills as if it were the same as Bone Butte? Unless maybe their talking about additional yet to be described discoveries in the site.
By the way do this restrictions extend to the names of the abstract or just content within it?

Even if this Leptoceratops was found within 100 meters the Dakotaraptor remains, there's still reason to be apprehensive because Saurian is only including animals within the last 300,000 years of the Cretaceous, which correlates with roughly the upper 3 meters of the Hell Creek formation. If this Leptoceratops is anywhere below that threshold, there's absolutely no reason to include it because it would be part of a different biota than the animals Saurian is working with.
I'm going to SVP to represent Saurian and do some digging for the Dev team in case anything is presented that might affect the game. We're already compiling a list of talks to attend that might affect things, including this one, so be sure to know we're going to clarify this and make sure everything is set. If something is presented that requires our attention, we will react accordingly.
Finally, while you won't get "in trouble" with anyone per-say regarding talking about the abstract's content in public places like this, it is generally frowned upon to do so without the author's permission, as the abstracts can only tell limited information and have no hard data and numbers to back up their claims by themselves. It's also listed in the abstract book itself to generally avoid talking about the abstract's contents in settings like this. I'd personally wait until the hard data presented at SVP comes out before discussing their claims: plenty of people (including myself) post about said data online after they're presented so there should be a glut of data available following the meetings.

hmm, maybe it's unpublished material? i have no idea to be honest
it's only the contents i believe, although i'll double-check

So cute, yet will probably make up most of my diet as a Dakotoraptor. Hmm

Looks like my ankles and feet will suffer with this around.

Such a chubby badass not-so-gracile Leptoceratops gracilis.
I love it, and I'm gonna buy saurian

I did a video on YouTube to get people to support the game. Here's the link: m.youtube.com/watch?v=Tdn--SK7…

Dude. Thank you so much for this. Leptoceratops is my favorite dinosaur of all time, and I'm incredibly happy it's in Saurian. Your style does the little guy justice, and then some. It's so nubby, oh my gosh <3 So hyped right now. Have a really good day!

That's looking good, but there should be some more jaw-closing muscles filling in much of the space on the underside of the protruding jugal.
👍: 0 ⏩: 2
Thank you very much, Scott! I will try to correct that soon.
👍: 0 ⏩: 1
You're welcome. It's so common in ceratopsian reconstructions I should probably do a blog post on it.
👍: 0 ⏩: 0
What is the name of those muscles?
👍: 0 ⏩: 1
There may be two - there's the near-certain presence of the adductor mandibulae (cf. "amev" in Sereno et al 2009 in Psittacosaurus, "mAMP" in Holliday, 2009). It's also possible that part of the ventral pterygoid that wraps around the base of the mandible actually inserts onto the back side of the jugal (sort of like Holliday suggested for hadrosaurs in the same paper mentioned above) though that's less certain.

Thanks Hartman!,is there a diagram showing the mAMP?

there are a few here (not for this taxa, though): onlinelibrary.wiley.com/doi/10…

Este siempre me ha hecho gracia, es como un jabali loro que si te descuidas te mete un bocado xD

ja, igual a como lo describo yo, también me hace pensar en un jabalí mezclado a un loro una tortuga mordedora

Man, Leptoceratops has such a damn big head and jaw. I love it! Nice choice of colors.
👍: 0 ⏩: 1
Leptoceratops is a lot bigger than I though, I love it. Can I ask why it is lacking quills?
👍: 0 ⏩: 2
I think you were responded below, no direct evidence. Not saying it's impossible, just a team decision.
👍: 0 ⏩: 1
I was thinking it was. Great color scheme though!
👍: 0 ⏩: 0
Maybe the Saurian Team didn´t want to speculate on that,sometimes this kind of structures (wattles ,feather tufts,etc) are not shared even in same genus species.Do we have evidence of the homology of the quills of Psittacosaurus and feathers?
Changing the subject,the tail of the Pachycephalosaurus is strange...They speculated on that.
👍: 0 ⏩: 2
We do have strong evidence that the quills are homologous in the form of Tianyulong, a basal ornithischian, and Kulindadromeus, which is currently the sister taxon to Cerapoda - a clade that contains ceratopsia. The current hypothesis is that feathers are basal to all of dinosauria (and perhaps Ornithodira if pterosaur pycnofibers are definitevely shown to be homologous) and so the integumentary structures of ceratopsians are feathers, and not an independently evolved feature.

Thanks
Is there a paper on the homology of quills in Tianyulong and Psittacosaurus ?Open access?
Tianyulong(Heterodontosauridae) and Psittacosaurus(Marginocephalia) share similar quills but not Kulindadromeus (Basal Neornithischia),it has more complex filaments (feathers) ,perhaps that´s because Kulindadromeus "feathers" evolved after quills in only in that genus.It would be amazing if theropod feathers and Kulindadromeus complex filaments evolved after the quills and ended sharing same function(Thermoregulation).
And yes, I support the current hypothesis,the filamentous integument (quills) are basal to all of dinosauria
👍: 0 ⏩: 1
The likelihood of Kulindadromeus feathers being independently evolved analogous structures is much less likely than a homological origin. Therefore it is the parsimonious conclusion that they share an origin and only Kulindadromeus evolved more complex feathers. It is interesting to note that quills very similar to those in Tianyulong and Psittacosaurus are present in the therizinosaur Beipiaosaurus.
I haven't read it since it came out but I'm pretty sure one of the conclusions of the paper that described Kulindadromeus is that its feathers are homologous to the integumentary structures of other ornithiscians, but forgive me if I'm misremembering it! Unfortunately the only open access paper I can find is a formal response by the authors to comments on the descriptive paper - this is only a few pages long and is concerned with the structure of the feathers rather than their evolution, so is unhelpful.

"The likelihood of Kulindadromeus feathers being independently evolved analogous structures is much less likely than a homological origin"
Not totally independently because in this hypothetical scenario they share the same origin,homologous quills basal to dinosauria.
"Therefore it is the parsimonious conclusion that they share an origin and only Kulindadromeus evolved more complex feathers."
This is what I tried to say,I don't know if I expressed me correctly
"share an origin" the quill-like filaments " and only Kulindadromeus evolved more complex feathers" This structures for example: www.evolutionnews.org/kulindad… I don´t know if theropod feathers passed through this phase
