Undescribed Dinos and Other Beasts

[ZoPteryx]

This thread is devoted to listing the various undescribed prehistoric beasts that we have heard in passing, either via rumor or unpublished abstracts.  It's not meant to be comprehensive, just listing those that are rather interesting or highly anticipated.  Feel free to post any undescribed prehistoric creatures you've heard of (preferably with a link) and I'll add them to the list.  As specimens are described they will be removed from the list.  I will do my best to keep this list updated!

[Dinoguy2]

Is this supposed to be a list of undescribed species, or just unpublished information in general? Most of the references you posted are just to talks people gave at conferences.

And some of these HAVE been published, like the Painten pro-pterodactyloid, just not given a formal name (in that one's case, because it's a hatchling).

A bit of both, anything that anyone might find interesting that is in the works but hasn't been properly published yet.

Didn't realize that one had been published, I've removed it from list.  What others have I missed?

[BlueKrono]

Ooh, this is tough. If it's I described there's a lot less chance we would have heard of it.

[Logo7]

I have quite a long list of things to add to this list. I'm not sure if you have some of them already, but I know that most of them are new. Most of them are nomina nuda, names of genera that have been coined but haven't been put into print. Even after I post this, you can expect even more follow-up posts when I find new unpublished discoveries to add to the list.

Since I lived in Utah for almost 7 years, I developed an interest in its underrated productivity when it comes to new dinosaur genera. I've read that this includes a few unnamed genera as well as the 39 currently named to my knowledge. The Dino Checker page for Mierasaurus talks about it having a couple of unnamed contemporaries:
-an allosauroid only known from teeth
-a polacanthid (they could be nodosaurids)
There's also a tyrannosauroid from the Mussentuchit Member at the top of the Cedar Mountain Formation, which has been more productive in terms of new dinosaur genera than other Utah formations combined, having 22 of the aforementioned 39 genera. This tyrannosauroid was mentioned by Lindsay Zanno in interviews after she announced Siats.
Some I've heard of from other formations around the state include a coelophysoid and another theropod from the Nugget Sandstone (specifically the Saints and Sinners Quarry) and an ornithopod and a pachycephalosaurid from the Kaiparowits Formation.
One clade I'd love to hear of a new member of is Albertosaurinae. I'm tired of it just being made of Albertosaurus and Gorgosaurus.

[Brontozaurus]

There's 'Lightning Claw', Australia's biggest theropod: http://www.australiangeographic.com.au/blogs/austropalaeo/2015/09/new-dinosaur-is-australia%E2%80%99s-largest-carnivore

The Australian Age of Dinosaurs museum in Winton has a ton of stuff they're still preparing, mostly sauropods, but there was a hint that there was a bigger carnivore than Australovenator, though I've heard nothing of it for ages.

[UtahraptorFan]

OT: Long time, no post. I'm just not as addicted to internet forums as I was as a teenager and in my early 20s.

I mentioned in my first reply to this thread my desire to see a new albertosaurine and I found a picture of an unnamed one from the Oldman Formation on Deviant Art. Here's the picture. I'm not sure if RLCM would be the initials of the museum and that's the specimen designation or not. In fact, all I do know about this specimen is what it says on the link I've provided.

I don't know if this list is still being updated, but if it is, I want to say that one of the items on it has finally been published. Specifically this one: "two new Early Cretaceous alvarezsaurs fill in gaps in the group's evolutionary history, Haplocheirus is confirmed as a basal member, possibly along with Aorun and Tugulusaurus (SVP 2016, pg 115)". This was published in August 2018 and resulted in the description of two new alvarezsaurids, Xiyunykus and Bannykus, as well as the new status of Haplocheirus, Aorun, and Tugulusaurus as basal alvarezsaurs. This should thus be removed from the unpublished list as soon as possible.

What are the requirements for posting in this part? Should the information only involve animal life? Should they have been commented on congresses?

My question arises from the fact that some Lives about paleontology are occurring in this pandemic period, and sometimes we get information from works that are yet to be published.

For example, in a live that I was watching, they showed a drawing by Julio Lacerda  that will illustrate a future paper about a fossilized grass found in Brazilian Cretaceous rocks.

Cretaceous grass from Brazil sounds really interesting and important! Personally I think that's an interesting addition to this thread.

I don't think this thread is being updated anymore. It hasn't been updated in quite a while. I started a revival of this thread here (http://dinotoyblog.com/forum/index.php?topic=7915.0) that is kept up to date with unpublished information. Anything, including the fossilized grass you mentioned, can and will be added to the revived list.

[VD231991]

I have quite a long list of things to add to this list. I'm not sure if you have some of them already, but I know that most of them are new. Most of them are nomina nuda, names of genera that have been coined but haven't been put into print. Even after I post this, you can expect even more follow-up posts when I find new unpublished discoveries to add to the list.

I don't believe this version of the thread is being updated anymore, which is why I posted the revival list in its place. Although my list on this thread is no longer as frequently updated due to the existence of my revived list, hence the general poorer quality of the sources used, I decided to update it here anyway just to ensure that nothing that had already been described was present on it. I've left "Microcephale" on the list for now though, as, although I'm sure you're right and I would love for it to already be published, I would need to see the email conversation referring it to Foraminacephale in question as a source before I feel confident with removing it. Other than that, everything else has been removed. Please keep letting me know if you see anything on any of these lists that needs updating.

This thread is devoted to listing the various undescribed prehistoric beasts that we have heard in passing, either via rumor or unpublished abstracts.  It's not meant to be comprehensive, just listing those that are rather interesting or highly anticipated.  Feel free to post any undescribed prehistoric creatures you've heard of (preferably with a link) and I'll add them to the list.  As specimens are described they will be removed from the list.  I will do my best to keep this list updated!

really good research ,iv heard of a few of these,but it goes to show there is still loads of new specimens that are still unknown ,just like i suspected..
since iv been a long time follower of dinosaur and others ,i do keep check of the major finds and some others of interest...im still surprised by a few of non dinosaur finds...but i do expect more mummified dinosaur specimens to be found...

The dinosaur informally dubbed "Merosaurus" in an unpublished manuscript cited by Stephan Pickering in his 1995 book has been officially named Dornraptor normani by Baron (2024).
