Great work making a little know dinosaur look so majestic and powerful!

Due to its size, it is likely that Spinosaurus has hunted this animal on certain occasions, although I think that fish were more their specialty, but if it is curious how animals of this period (both a predator and a herbivore) have developed underwater adaptations. Although as you say, it is possible that Spinosaurus has only seen the last Lurdusaurus

To be really honest I did not expect Spinpsauridae 'Inner Group'' Spinosaurinae (Spinosaurus closest relatives) to show direct and validated evidence for Generalist Carnivore behaviore; yet we have at least two Spinosaurinae, İrritator and Siamosaurus that have shown clear-cut evidence for this particular situation.
▪In the case of Siamosaurus, appearently; there are several instances of isolated tooth crowns from Siamosaurus have been found; in direct association with sauropod remains, indicating possible predation and/or scavenging, from the Sao Khua Formation of Thailand.

▪In the case of Irritator; apart from the Famous irritator teeth on large pterosaur case; www.nature.com/articles/430033…

there is a recent study established The Spinosaurinae being the Apex Predators of their ecosystems; directly based on this unique spinosaurid !
The researchers established that the diet of spinosaurines in these types of environments include large pterosaurs, terrestrial and aquatic crocodyliforms, and (Terrifyingly!) juveniles of their own species(!), turtles, and small to medium-sized dinosaurs. This would have made spinosaurines apex predators within their ecosystems
*I particularly found this study as a massive stepping stone for Spinodauridae & Spinosaurinae

To be short (sorry about the extensive cases ) Spinosaurus Aegptiacus definetly showed a behaviore far much more equavilent to Crocodilians with elongated snouts /such as Orinoco Crocodile and False Malaysia Gharial/ and Bears; rather than extremely specialized animals.
So; in a speculative scenerio; where a Hungry 15.5 - 16.5m Spinosaurus encountered a lone, isolated Ludusaurus on a Mangrove/Marshland Swamp - or directly at river, the result wouldn't be pleasing for the Iguanadontid
Maybe the First Spinosaurus directly compete and consume the Last Remaining and Stagnating Ludusaurus'es that occupied the niche before them; sounds dramatic
*In addition; Both Mawsonia and Onchopristis were massive multiton animals; if a theropod could hunt them; it would be extremely illogical/paradoxical to assume it couldn't hunt other prey with similiar size

Me encanta este dinosaurio! Hace años hice un igaunodontido evolucionado parecido a este que adopto la vida anfibia.
