Theories on The Horror Mouth

As many of you know, an extremely poorly known spinosaur nicknamed "The Horror Mouth" was discovered at one point, but like every-frickin'-other awesome giant African carnivore (Saurophagus, Spinosaurus, Bahariasaurus, unnamed megalosaur) was destroyed in an allied bombing in Germany in 1944 before it could become famous or even be scientifically described. From what little information I've been able to dig up on it over my two year quest for knowledge regarding "The Horror Mouth", it appears it was discovered in 1944 in Niger, Africa and it would have lived alongside the comparably-sized Suchomimus. Some vertebrae also show it may have had a sail similar in relative size to that of the larger Spinosaurus. Which is where my theory comes in. With the revelation that the largest and possibly only Suchomimus specimen known is a subadult, I came up with a theory. The Horror Mouth may be an adult Suchomimus. The sail would have gotten taller throughout life and the teeth would have changed size. The projected adult size if Suchomimus matches perfectly with the estimated size of The Horror Mouth. My only problem with this theory is skull shape. The jaws of Suchomimus are thinner than those of The Horror Mouth and the teeth are more numerous. The lower jaw of Horror Mouth is wider than the upper jaw at some points and vise versa. Another theory I have is that The Horror Mouth simply never existed. Perhaps teeth of an adult specimen were found near the skull of a subadult and were attached to the drawn out reconstructed skull. For the reason that this theory would mean Suchomimus had the longest teeth of any known carnivore(~14 inches including the root) I disregard it. Bonus News: DinoFights' sister's team is setting out on an expedition to Africa to attempt to find fossils of "The Horror Mouth", "The Snake Eater"(I requested it be named Serpentinethantus), Spinosaurus and any other dinosaurs in a few weeks. What are your theories on/names for The Horror Mouth?
