Doubtful dinosaur species

[Concavenator]

Hi all ,
I have started a topic 'bout doubtful dinosaur species.There are a number of doubtful dinosaur species,which can belong to other genres,or they are misterious,or difficult to classify.In this topic we can share these doubtful dinosaurs,comment of their toys,and share our opinions about this varied group who
pics very different species.Some doubtfuls species I know are:
Saurophaganax,Yaverlandia,Jobaria,Dracorex,Asiamericana,Ceratops,Stegosaurides.If I discover more,I 'll post them.
(I know that Yaverlandia is a valid specie,but I don't know if it is a pachycephalosaurid or a maniraptoran.If someone could explaim it me ,I would be grateful)

We have some of the notes and papers on Yaverlandia bitholus, the specimen was discovered in 1923 close to the village of Yaverland on the Isle of Wight, the holotype material was fused cranial material - frontals, post-orbital etc.  The frontals show thickening and it was from this evidence that the Pachycephalosaur link was made.  Having a domed skull like a Pachycephalosaur.  However, such fragmentary material does not make assessing the taxonomy of a specimen that easy, its affinities to the Pachycephalosauridae or any other dinosaur family is speculative.

Thanks answering!

I thought it might be interesting to pick the "best" of each line. I don't have the expertise to debate the accuracy of different figures but these are my favorites from each manufacturer for various reasons.

I think you posted this in the wrong place...

How about Saltaposuchus?  Maybe not a dinosaur but a bipedal croc.  It also has 2 two figures.

[tanystropheus]

Ultrasaurus, Monoclonius, Brontosaurus....

[Brachiosaurus]

Does Augustina technically count now?

[Splonkadumpocus]

Does Augustina technically count now?

No, it's a perfectly valid genus. It just didn't have the big spikes.

[DC]

How about Teratosaurus, Seismosaurus,  Ultrasauros, Agathaumas, Trachodon, Hadrosaurus, Shuvisaurus

I believe many people consider Monclonius valid.

[tyrantqueen]

Antrodemus?

Since Antrodemus was named before Allosaurus, shouldn't that be the correct name?

Also: Phobosuchus, Dynamosaurus imperiosus, Manospondylus gigas.

[amargasaurus cazaui]

 Antrodemus became the accepted name for this familiar genus for over fifty years, until James Madsen published on the Cleveland-Lloyd specimens of Allosaurus and concluded that name should be used because Antrodemus was based on material with poor, if any, diagnostic features and locality information (for example, the geological formation that the single bone of Antrodemus came from is unknown).[4] Subsequent authors have agreed with this assessment and have considered Antrodemus a nomen dubium.[5][6]

Teratosaurus and Shuvosaurus are valid genera. They're stem-crocs, though, not dinosaurs.

Also, Hadrosaurus was redescribed in 2011 and found to be distinct.

How is Jobaria a doubtful genus? Over 95% of its skeleton is complete, and I have found no sources doubting its validity.

[CAWCarcharo]

What about Allosaurus lucasi and Allosaurus jimmadseni? A. lucasi in my opinion is just an Allosaurus fragilis but it's apparently valid; though A. jimmadseni seems a bit more plausibly valid but isn't currently valid. Any thoughts?

[AcroSauroTaurus]

To update this thread further, both Saurophaganax and Monoclonius are now valid.
