Sorry to burst everyone's bubble..no new finds here..lol
I just wanted to ask, I'm starting a 9' - 10' Spinosaurus (juvenile ) sculpture and I'm curious what features it might have different than the adult. I can't find many references online for one of that age.

Well as far as I know there aren't any fossils officially dubbed a juvenile spinosaurus on record. If I had to guess I would say perhaps make the sail less prominent?

Also the usual juvenile features. Larger orbits, no or small head crest, shorter snout, etc. Would it have fuzz? I would look at an adult and baby gharial or crocodile for head shape changes.   |

I'd be inclined to err on the side of caution and not include it. If fuzz was basal within the Dinosauria or Ornithodira then, maybe...although apparently a scaly baby allosaur has been found. One other thing - how old is this juvenile going to be? I'm sure you're aware, but that would obviously affect things like sail height. |

Thanks for all your input !
That's the thing..it will be 9-10' feet long..so hard to say just how old..obviously walking around on it's own but maybe still traveling with it's parents ? With no good fossil evidence to go by it's hard to say. It 's def not mating age..and not a stumpy hatchling either. There just isn't a good gradient from hatchling to adult with them being so rare.
I'm think slightly larger eyes..maybe shorten the sail a bit, I'm also considering just barely shortening the jaws...but at a length of 10' would all that make sense ?
I really wanted to do a Spinosaurus but not a tiny version of the adult since I like 1/1 scale...a juvenile should be good. I think it's makes more sense they would have those baby features found in birds and some reptiles .
Wow..any more info on that baby Allosaur !?

Yeah, sorry, read your original post incorrectly (I thought you said that you wanted to make a 9 or 10 INCH model for some reason). Given that it's less than 1/4 grown, the sail should probably be dramatically reduced from adult size.

No problem. I like to do things big..if possible..lol
So the idea is the sail would prob grow throughout the animal's life ?

I would also recommend giving it rather cryptic coloration; lots of big predators in Cretaceous north Africa. Also, based on crocodile hatchlings, I would give it slightly smaller teeth than what the adult would have.

I can do that. I haven't settled on a coloration yet..but something less stand-out-ish makes sense.

The Baryonyx type specimen wasn't fully grown when it died, and has a lower 'sail' than the larger Suchomimus, which some think should be lumped into Baryonyx (as B. tenerensis). Of course neither had a sail like Spinosaurus, but one can see a parallel there. |

I've been wondering just how many different species there might be...we just don't enough material I guess for spinosaurs. Bary could have looked a lot like Spino or Sucho when full grown. Is it still possible Suchomimus is a female Spinosaurus or just not an adult one ? Heard that mentioned a long while back.

The Baryonyx type specimen wasn't fully grown when it died, Based on fusion of the vertebrae, all known spinosaurid specimens are subadult. I'm beginning to suspect they were just bit paedomorphic and maybe the verts never fully fused in mature adults for whatever reason... |

Maybe it has something to do with making those spines more flexible than thought ?

You read my mind ! That was exactly the monitor species I was thinking of too.. and I do LOVE the orange/yellow and black on theropods..it's also very " Halloween-ish " ;D
The duller pattern made sense too..but Spinos feel a bit more...reptilian to me for some reason.
I'm also tempted to paint a mosasaur like that.. ;D

I posted some new pics in the art section..I think the head may be too small. I'd like to know what you guys think.

Still working on my Spinosaurus,,but I have a question. My Dad came in today with a Spinosaurus tooth he bought at the flea market. It came in it's own little case and such with " certificate " and all but I know Spinosaurs are rare fossils in the first place and I read they're teeth are often confused. mixed in and sold with fossil croc teeth from the same area...so it seems there a LOT of Spinosaurus teeth. So my question is, How do you tell a croc tooth from a Spino tooth ?
