Oxalaia

(Oxalaia and Yutyrannus)

Just need to make a couple more, color them, and give them names

If you guys have name ideas or color suggestions to give, I would greatly appreciate it

On the Pacific Island of Isla Deinonia, or, the Terrible Island, we have a rich and biodiverse Valley, located in Central Deinonia west of the Sierra Giganus.

Caption: A map of Isla Deinonia, with the Valley circled in red and a legend.

On Isla Deinonia, nineteen unique species coexist, with an additional nine subspecies in the form of variants.

Going numerically, we go to number 4, the Deltas. Here we can find Highspine (Variant B), Fishtail, and Turtleshell.

A male (top) and female (bottom) Highspine (Variant B).

Highspine (Variant B)

Height: 10'6" ft

Weight: 6.5 tons

Length: 53'6" ft

Diet: Carnivore/Piscivore

Predators: None

Code: HSB

Inspiration: Oxalaia (2014)

Range: Deltas

Notes: The Highspine (B) is a formidable piscivore in the terrestrial deltas, hunting large sawfish and Turtleshells. They walk on their front limbs to account for a smaller tail. They mostly live in pairs, though when threatened they have been known to defend in groups of three. They are much more specialized and brittle than their northern counterparts. They rarely- though they do- interact or fight with Fishtails, despite sharing the same prey.

Fishtail

Height: 6'5" ft

Weight: 16.8 tons

Length: 46'8" ft

Diet: Piscivore

Predators: None

Code: FT

Inspiration: Tylosaurus

Range: Fish's Folley, Turtle Bay, Deltas

Notes: The Fishtail is an apex predator of the waters, interacting with other piscivores such as Lowspine, Highspine (Both Variants), and Wingfinger (All Variants). Males earn the affection of mates through the brightness of their heads.

A male (top) and female (bottom) Turtleshell.

Turtleshell

Height: 3'8" ft

Weight: 3.5 tons

Length: 13'6" ft

Diet: Piscivore/Herbivore (Kelp and Jellyfish)

Predators: FT, LS, HSB, HSA, WFA, WFB

Code: TS

Inspiration: Archelon

Range: Turtle Bay, Deltas, Fish's Folley

Notes: Turtleshells get a rough life. They are a primary source of coastal prey for Wingfinger, Fishtail, Highspine, and Lowspine, and while rare, they can be preyed upon by coastal predators, such as Humpback and Necktooth. Even though they have a hardened shell, they're still preyed upon constantly.

Thank you for listening to my TED Talk, and have a good day.

The Sailfin Dinosaur (Scientific name is Austrospinus Crocodylus, meaning "Southern Spine", with the specific name referring to Crocodiles) is a Spinosaurid from South America. It might have evolved from a Spinosaurid similar to Oxalaia, but it's smaller and the tail fin in less pronounced. They live mostly on land, and they only go underwater to catch fish.

Although it's smaller than it's ancestor Oxalaia, Austrospinus is still a fairly large dinosaur.

What makes a dominant species? The question is incredibly broad, so to help us all out, here are some rules:

-The species must have been on top of its food chain

-The species must have lived the longest, compared to its relatives

In addition, if these specifications were not enough, the comparison of ammunition should also be considered; which animal had the most deadly claws, or other features.

I remember doing a presentation in high school on which spinosaurid was the most dominant in its geological timeframe. I compared information gathered on wikipedia between the species. Which one had the least competition, had the most, carnivorously dominant traits, and duration of the species existence.

My final, unbiased, answer, was Oxalaia, a long time ago.

I was really young at the time, I have not educated myself on the recent evidence regarding this family of prehistoric reptiles, may someone inform me about my, most likely incorrect, analysis, and how off I was at the time?

Edit: I used the Angaturama Holotype, it should be SMNS 58022 for Irritator not USP GP/2T-5

If you want the sizes, I gotchu

Spinosaurus aegyptiacus-14.5 Meters, 8.35 Tonnes

Suchomimus tenerensis-12.14 Meters, 5.4 Tonnes

Siggilmassasaurus brevicolis-11.7 Meters, 4.7 Tonnes

Riparovenator milnerae-10.54 Meters, 3.32 Tonnes

Oxalaia quilombensis-10.3 Meters, 3.32 Tonnes

Baryonyx walkeri-8.5 Meters,1.7-2.5 Tonnes

Ichthyovenator laosensis-8.5 Meters, 2.2 Tonnes

Irritator challlengeri-5.6? Meters, 1 Tonne

And no shitty tooth taxons are allowed here(Yeah may seem hypocritical to say that while adding Oxalaia and Siggilmassasaurus but Siggilmassasaurus is a cooler name than Spinosaurus and I wanted to use a quad Spino somehow)

All these drawings are based on these wonderful skeletals
