Spinosaurus mirabilis
“ At the start, I told my team — girding them for the certain hardships and extreme conditions we would soon face — ‘This is our chance to write a chapter in the history of Africa's dinosaur world, and sometimes that chance comes along only once in a lifetime. ”

Spinosaurus mirabilis is a large extinct species of the spinosaurid theropod dinosaur genus Spinosaurus, known from the Late Cretaceous Farak Formation of Niger.
Shatimse is the term from the two languages from Egypt: Arabic and Egyptian. Timsah (تمساح) means crocodile and šw (sheu), is the plural word for river. Which is word was not from Moses.
Spinosaurus have been named: Spinosaurus aegyptiacus (meaning "Egyptian spine lizard")
Unlike their related Spinosaurus aegyptiacus, which has a comb-shaped crest on their head, Spinosaurus mirabilis had a long, low snout, a scimitar-shaped midline crest on the top of the skull, and a wide sail over the back. Compared to Spinosaurus aegyptiacus, this animal had longer limbs, a longer tail, and a different-shaped sail.
Similar to its relatives within the Spinosauridae, it had large, powerful arms and enormous, hooklike claws for grabbing prey, much like modern bears do today.
Spinosaurus are very strong, fast (especially in water) and have a fair amount of health. Do not attempt to escape one by running into water, as their height advantage and swift swim speed make this usually successful strategy foolhardy in the extreme. If in water against a Spinosaurus, pray you can get to shore or sink out of its reach and hope you can escape it on land.
Manipulative and intelligent when in the water and using the snout and fangs to cause bleeding.
Using a Sonic Bomb is an easy alternative to fishing out a Spinosaurus. Just be cautious that it will enter rage mode upon recovering.
Spinosaurs can now defeat dinosaurs like the sauropods and huge theropods with ease. This is because of its brand-new bipedal mode and water buff, which boosts its destructive power. The Spino drowns quickly for a semi-aquatic creature, so avoid knocking it out in water while taming it. They will frequently ignore you while you are on an ichthyosaur or a dolphin until you are almost touching them.
It was primarily a piscivore (fish-eater), though it probably sought or scavenged smaller terrestrial meals when needed. Carcharodontosaurus was their primary opponent. It deposited eggs, much like every other theropod. Although no unique Spinosaurus nests have been found yet, it most likely nested close to riverbanks.
In terrestrial nests close to the water's edge, Spinosaurus most likely lay its eggs. There is little proof, but like many reptiles, it might have offered some degree of parental protection:
Egg-laying (like all dinosaurs)
Nested near water bodies
Young may have been semi-independent early, similar to reptiles today
No direct fossilized nests confirmed yet
Spinosaurus was probably a shallow-dwelling ambush predator. Tooth marks on the sails of other examples showed how fiercely territorial it was. You wouldn't want to encounter one. Its sheer size and territorial instincts would turn any riverside into a death trap, even though Spinosaurus might ignore you for a large fish. A human or other non-fish animals would be seen by a Spinosaurus as a snack or an annoyance that should be snapped at.
While the K-Pg asteroid eventually finished off the dinosaurs, Spinosaurus likely vanished earlier due to sea-level changes or possibly asteroid struck. As the massive river systems of North Africa dried up or became marine environments, the specialized "river monster" lost its niche.
Possibly asteroid impact (Chicxulub)

Ecosystem breakdown
The competitors of the century, Spinosaurus mirabilis and Carcharodontosaurus saharicus, lived in the Farak Formation, a geological formation in Niger, central Africa. During the Early Cenomanian period of the Mid-Cretaceous, this geological formation existed in a humid, tropical, fluvial-lacustrine environment.

As mentioned in dangers, Spinosaurus can step over 2 walls high. This means it will not be stopped by such obstacles, including the Billboard or poles. If you plan to use traps, make sure it is tall enough.
Using tranquilizer darts or bullets, including sleep bombs to make unconscious and feeding with narcotics and meats altogether. Then you climb up on the back of a spinosaurid once it has landed. If you give a fish or piece of flesh to a spinosaurid, it will take off, but don't worry, you won't fall. The third person is now in view. After the initial feeding, pause for a brief period before feeding it again.
Alternatively, to tame a spinosaurid, survivors must grab one of its eggs. The kids must be fed any kind of milk after hatching from these eggs, which can be obtained from a variety of sources. The fact that the survivor is always within 10 radii of the hatching egg causes all spinosaurids to become domesticated as soon as they emerge from an egg. The spinosaurid can be educated using a whip, worms, animal flesh, fish wrapped in seaweed, or fish eggs if it hasn't already been.
Paul Sereno, who is credited with describing prehistoric species, is the primary ally and bestfriend of Ronaldo Kealani and Marianne Jorpassadal from the No Way to Seaway series, Rapunzel's Tangled Adventure, and Assassin's Creed series. However, in the Earth Responsibly universe, he comes across living prehistoric animals from the Mesozoic era that are brought by the Isu Collider Gateway in Siberia. These animals are arrived via the device was connected to the Global Shield Device in New York State, which Clay Kaczmarek wishes to sacrifice, but as a save to his relative Desmond Miles in order to survive, and Lucy Stillman is accidentally resurrected after she is canonically killed by Juno or Hera that Desmond was cursed by the bad "goddess".
In 2013, only Spinosaurus aegyptiacus was known to exist. However, since 2019, there has been another species of Spinosaurus whose crest has been longer than anticipated and whose look does not match that of its Central African habitat. The Hidden Saviors discovered that this species desires frequent feeding and study.
