Beta

Beta is a fire-attributed Acrocanthosaurus and is Ace's old alpha before joining the D-Team.

## Character design

### Personality:

Beta is very aggressive and is very level headed, but she doesn't mean to. It's all part of her being an instinctual carnivore. When the time comes she can be seen as mournful for the loss of her family from her home land and misses them greatly. She shows a deep connection with Ace as she was his old alpha who banished him from her pack because he would most often mess up his hunts, but regretted it dearly, so much so that after the D-Team rescued her from becoming Alpha Acrocanthosaurus, she stepped down as alpha as forgiveness to Ace, thus, becoming his mate.

### Anatomy:

As an Acrocanthosaurus, Beta is measured 11 m (36 ft) from snout to tail tip and weighed 5.7 to 6.2 metric tons (6.3 to 6.8 short tons), with an upper maximum weight of 7.25 metric tons (7.99 short tons). her skull alone was nearly 1.3 m (4.3 ft) in length.

### Skull

Beta's skull, like most other allosauroids, is long, low and narrow. The weight-reducing opening in front of the eye socket (antorbital fenestra) was quite large, more than a quarter of the length of the skull and two-thirds of its height. The outside surface of the maxilla (upper jaw bone) and the upper surface of the nasal bone on the roof of the snout were not nearly as rough-textured as those of *Giganotosaurus* or *Carcharodontosaurus*. Long, low ridges arose from the nasal bones, running along each side of the snout from the nostril back to the eye, where they continued onto the lacrimal bones. This is a characteristic feature of all allosauroids. Unlike *Allosaurus*, there was no prominent crest on the lacrimal bone in front of the eye. The lacrimal and postorbital bones met to form a thick brow over the eye, as seen in carcharodontosaurids and the unrelated abelisaurids. Nineteen curved, serrated teeth lined each side of the upper jaw, but a tooth count for the lower jaw has not been published. *Acrocanthosaurus* teeth were wider than those of *Carcharodontosaurus* and did not have the wrinkled texture that characterized the carcharodontosaurids. The dentary (tooth-bearing lower jaw bone) was squared off at the front edge, as in *Giganotosaurus*, and shallow, while the rest of the jaw behind it became very deep. *Acrocanthosaurus* and *Giganotosaurus* shared a thick horizontal ridge on the outside surface of the surangular bone of the lower jaw, underneath the articulation with the skull.

### Postcranial skeleton

The most notable feature of beta;s species was her row of tall neural spines, located on the vertebrae of the neck, back, hips and upper tail, which could be more than 2.5 times the height of the vertebrae from which they extended. Other dinosaurs also had high spines on the back, sometimes much higher than those of *Acrocanthosaurus*. For instance, the African genus *Spinosaurus* had spines nearly 2 m (6.6 ft) tall, about 11 times taller than the bodies of its vertebrae. her lower spines of had attachments for powerful muscles like those of modern bison, probably forming a tall, thick ridge down its back. The function of the spines remains unknown, although they may have been involved in communication, fat storage, muscle or temperature control. All of hrt cervical (neck) and dorsal (back) vertebrae had prominent depressions (pleurocoels) on the sides, while the caudal (tail) vertebrae bare smaller ones. This is more similar to carcharodontosaurids than to *Allosaurus*.

Aside from its vertebrae, beta has a typical allosauroid skeleton. Beta is bipedal, with a long, heavy tail counterbalancing the head and body, maintaining its center of gravity over its hips. her forelimbs were relatively shorter and more robust than those of *Allosaurus* but were otherwise similar: each hand bore three clawed digits. Unlike many smaller fast-running dinosaurs, her femur was longer than its tibia and metatarsals, meaning beta was not a fast runner. Unsurprisingly, her hind leg bones were proportionally more robust than its smaller relative *Allosaurus*. her feet had four digits each, although as is typical for theropods, the first was much smaller than the rest and did not make contact with the ground
