hallo my name is Peter and some of you guys already know me, especially you David and Daniel. this is my first time on this forum, and I am very glad that I can join it. few months ago I found near Oxford in a quarry called Woodeaton quarry remains of a stegosaurid dinosaur, which is probably a new genus of a dinosaur. unfortunatelly I didn't found any diagnostic material so it will be quite hard to describe this animal. the material includes an ilium, some ribs, few dorsal osteodermal plates, and a process of a probably dorsal neural arch. if is somebody interested I can send some pictures on e-mails of the bones and fossilsite. please let me know on my e-mail adress -
paleo23@gmail.com or here at the forum.
and one more thing, I was for two times in Krasiejow but I don't remember any Polish, so please, write to me in English. thank you.

Na proĹbÄ Marcina zamieszczam tĹumaczenie:
Witam, nazywam siÄ Peter i czÄĹÄ Waszych kolegĂłw zna mnie, zwĹaszcza ty, Dawidzie [Mazurku
] i Danielu [Madzia :D]. To jest moja pierwsza wizyta na tym forum, i jestem bardzo zadowolony, Ĺźe mogĹem siÄ do niego doĹÄ
czyÄ. Kilka miesiÄcy temu, znalazĹem w pobliĹźu Oksforfu w kopalni zwanej Woodeaton kopalne szczÄ
tki stegozaurydowego dinozaura, ktĂłre naleĹźÄ
pradopodobnie do nowego gatunku. NieszczÄĹliwie, nie znalazĹem Ĺźadnego diagnostycznego materiaĹu, wiÄc bÄdzie ciÄĹźko opisaÄ to zwierzÄ. MateriaĹ zawiera: koĹÄ biodrowÄ
, kilka osteoderm grzbietowych, oraz wyrostek prawdopodobnie Ĺuku krÄgowego. JeĹli ktoĹ jest zainteresowany, mogÄ przesĹaÄ kilka zdjÄÄ skamieniaĹoĹci i miejsca znalezienia na e-mail. ProszÄ daÄ mi znaÄ na mĂłj adres -
paleo23@gmail.com, bÄ
dĹş tutaj, na forum.
I jeszcze jedna sprawa - byĹem dwa razy w Krasiejowie, ale nie pamiÄtam polskiego, wiÄc proszÄ, piszcie do mnie po angielsku, dziÄkujÄ.

Peter, please, be careful with your classification. ;) It's difficult to say whether the animal is a stegosaurid. It's a thyreophoran but we aren't sure about its position among "armored dinosaurs". As I already wrote you, it's horribly preserved and highly incomplete. Moreover, we can't be sure (well, I can't be sure, because I haven't seen it personally) whether your "stegosaurid" isn't chimaera. You've found many indeterminable fragments from different places (or am I wrong?).
Peter.Agricola pisze:a process of a probably dorsal neural arch.
I would even say (based on the picture you've sent me) that this process is incomplete spinous process of a dorsal vertebra. But again - I'd like to see it from different sides and under higher resolution... Personal examination would be the best though.
Peter, give me one complete dorsal vertebra and I will tell you if it is a stegosaur
Okey, I'm joking, but something like that would be pretty good.
Finally, it possibly is a new genus and species of thyreophoran dinosaur, but I can't tell you more till I see it...

Heh! Ale ciagle wszystko wszedzie "szuka".

ok, but the osteodermal plates are typical for a stegosarian and, about the process, you know, that I will show you all bones this summer, if we don't meet in Krasiejow, you can come to Slovakia, or I can come tu Trinec. we will see. so we have to mannage a meeting.

Generally, "dermal armour" (i.e. plates or spines, and scutes [series of pyramidal scutes are present in
Scelidosaurus and ankylosaurs]) is synapomorphy of Thyreophora. But yes, plates and/or spines are synapomorphy of Stegosauria, which doesn't mean that your dino is a stegosaurid. ;)
But again - we are not sure (well, well, well... I'm not sure...) that the dermal armour you've found are typical "plates". The pictures are not convincing. ;)

I hope so.

yes, but I saw the plates for so many times, that I don't have any doubts that I am right. and especially Susannah Maidment, Angela Milner and Dave Martill suggested that they are stegosaurian. Don't worry, now we know, that we will meet in Krasiejow, so I will bring the bones there.

Then you are much more competent than me. ;)

"Stegosaurian" is not the same as "stegosaurid". The former is member of Stegosaur
ia, and the latter is member of Stegosaur
idae. If the dino is closer to
Stegosaurus than to
Ankylosaurus, then it is member of Stegosauria. If it is closer do
Stegosaurus than to
Huayangosaurus, it is a stegosaurid. If it isn't descendent of most recent common ancestor of
Stegosaurus and
Huayangosaurus, then it is non-stegosaurid non-huayangosaurid stegosaur[ian]. ;)
Of course, if they suggested that you have a stegosaur (or stegosaurian - both are correct), it doesn't mean that it isn't a stegosaurid.
