The movie back to the future is my favorite ever which inside got one part really suitable for people who saying me are fully talking nonsense. I can only say that the more embryo you handle the more you trust they are real! You guys might not yet ready to accept this new idea nw

@cannerygrow @W_A_S_D_Trike Possible also

@GooCheeEng1 @W_A_S_D_Trike I perceive the location of the nostrils being farther back is because its skull got shorter toward the front, meaning with its retracted position, its elevated in height. Either this or just a vestigial feature left over from more primitive spinosaurids that were waders

Did Spinosaurus also contain cervical osteoderms (neck scute) like modern crocodile and iguana? Find more in below article: petrifiedembryology.wordpress.com/petrified-embr… Note that study of dinosaur embryo belongs to red zone in current paleontology, like on your own risk.

@cannerygrow @W_A_S_D_Trike It looks to be hunting from top of water than under the water frequently, according to its location of nostrils.

@GooCheeEng1 @W_A_S_D_Trike The spines should not be a huge issue, as it would likely keep spinosaurus steady. I'm not sure why the nostrils are positioned so high, but does not seem to be for hunting purpose because of how deep the Kem Kem rivers were

@cannerygrow @W_A_S_D_Trike Not so sure, but its location of nose and long dorsal spine suggested that.

@GooCheeEng1 @W_A_S_D_Trike I mean it is possible, but it doesn't seem very efficient to hunt lungfish from the edge of a 6 meter river

@cannerygrow @W_A_S_D_Trike I also not so sure, but I think they only hunt in river side way. Is difficult to imagine as we are not in that era already.

@GooCheeEng1 @W_A_S_D_Trike Wouldn't the Kem Kem beds be too deep for hunting from the top of the water? Or was dorsojuvencus found in earlier strata?

@cannerygrow @W_A_S_D_Trike Because of its spine pattern, the long spines likely help prevent back muscle fatigue when the animal remains stationary while hunting on the water’s surface. For this reason, it may also suggest that Spino hunted more often on top of the water rather than immersing itself deeply

@GooCheeEng1 @W_A_S_D_Trike why?

@cannerygrow @W_A_S_D_Trike I think they would not hunt for a long time.

@GooCheeEng1 @W_A_S_D_Trike You mean it would not hunt underwater or it would not hunt for a long time?

@cannerygrow @W_A_S_D_Trike emm..may be but I think Spinosaurus seldom go underwater for a long period of time.

@GooCheeEng1 @W_A_S_D_Trike I have never thought about that, but considering crocodilians can use their osteoderms for neutralizing carbon dioxide underwater, it seems very plausible for this to be a use case for spinosaurus

@cannerygrow @W_A_S_D_Trike Potential just a convergent evolution, but Theropod with rough skin or embedded scute are likely occur more on rough skull surface dinosaur or dinosaur type that lack of lips pattern like crocodile skin, under my opinion.

@GooCheeEng1 @W_A_S_D_Trike It doesn't look like a feature scale, and seems way different than other theropod scutes. Maybe convergent evolution or a common ancestor between the two groups in Aliacollisauria? It still seems to be Dorsojuvencus more likely than anything.

@cannerygrow @W_A_S_D_Trike That’s about it. Unfortunately, I haven't found any evidence of these scutes on the fossilized bones. It’s possible they were similar to the skin integument of abelisaurids like Carnotaurus—feature bumps or structures that lack a bony osteoderm

@GooCheeEng1 @W_A_S_D_Trike Looks very reminiscent of saltosaurus mosaic scutes, and its relatives like paralititan also might have had them. It looks athough to overlap with the cervical scutes of the embryo, are there any other significant details about it?

@cannerygrow Is from me.

@cannerygrow Thanks and Great work!

@GooCheeEng1 Recently petrified embryology has been very accepted some micro communities in paleontology, with art and also pushing the ideas more, while also criticizing lazy criticism of your work :)

Rare Spinosaurus skull left quadrate bone compare to my hand. Thank you for support my hobby webpage, Petrified Embryology.

@cannerygrow Ya, can be say so.

@GooCheeEng1 So something more similar to the manucci 2020 3d model?

Well, we have a close look of how the sacral vertebra Spinosaurus connect to proximal caudal vertebra (tail). A. Isolated sacral vertebra, GCE2005277999 (or old code FOS7MORO); B. Proximal caudal vertebra, GCE2104146785 of Spinosaurus dorsojuvencus. Both specimens from Morocco.

@Darknightofark I think so. skinny species.

@GooCheeEng1 Right but would this lead to a more slim and semi aquatic model of the neotype?

@Darknightofark to me the neotype bone shows a lot of pneumatic hole, while dorsojuvencus appear less on that morphology. potential more like weight?

@GooCheeEng1 just for clarification sake, would the neotype have some of the of the traits Ibrahim proposed, e.g: wide/deep torso, lack of pneumatic bones in comparison to therapods that dorsojuvencus seems to exhibit more strongly?

@Darknightofark I'm also not very sure my friend. But one thing can be sure the anterior part of few dorsal vertebra of Spinosaurus will frequent found have a very deep area on the centrum vertebra probably they are derivative from the same ancestor like the sauropod.

@GooCheeEng1 what about dorsal vertebrae? would it still limit an air sac system and hold a deep torso?

@Darknightofark @W_A_S_D_Trike not very sure my friend

@GooCheeEng1 @W_A_S_D_Trike so the collected femur is spinosaurus P?

Under rebuild the limb bone of Spinosaurus dorsojuvencus from various composite material (not in size). The height of this arm is about the size of adult.

@Darknightofark Yes, from my point of view, the neotype shows emaciated vertebrae, and the cervical vertebrae appear slowly evolve into skinny, somewhat slightly raptor-like in proportion.

@GooCheeEng1 also does your comparisons with dorsojuvencus and the neotype contradict with the claim that aegyptiacus was apneumatic

@Darknightofark @W_A_S_D_Trike Attached is the potential how the forelimb of Spinosaurus look like. From my study of Spinosaurus the evidence shows that Morocco have at least 3 type of Spinosaurus. The neotype is completely new species. Your new photo to me is Spino femur, likely different species from neotype

@GooCheeEng1 @W_A_S_D_Trike if you also don't mind I see this image of a collected Spinosaurus femur to say that Spinosaurus did not have a C shaped femur despite in my opinion not looking like the neotype's

@Darknightofark @W_A_S_D_Trike This one is quite impressive, like me they are build from composite. Its small thumb bone should be leg phalanx. The humerus are likely cast. The ulna probably from Carcharodontosaurid. The radius never see before, not very sure belongs to what species but overall is still nice:)

@GooCheeEng1 I have seen this photo people have been spreading of this unidentified fossil collector to say that Spinosaurus had short arms. Do you think this is a different species or a younger Spinosaurus? @W_A_S_D_Trike think it's fake

@Darknightofark @W_A_S_D_Trike I think that estimation is based on its jaw growing pattern. The teeth socket appear to be continuous replace by larger teeth and the size is continue turn larger. Not based on the embryo

@GooCheeEng1 @W_A_S_D_Trike right, but another fascinating thing I found in the 3rd embryology book is the claim is that you said Spinosaurus grew its entire life, is this only from emb1moro or other sources?
