I decided to open a topic for this continent, since it was the only one that remained without one in the foreign section.
I was thinking about the possibility of the snakehead fish and the peacock bass, both introduced species in the USA, surviving in the Neocene. Does it seems plausible? Another animal that could live here is a descendant of the house sparrow. It was also introduced here.

The Neocene already have a desert deermara, but living in the Mexican Plateau as an analogue to gazelles.

In russian version their areal is bigger: deserts and savannas of North America, and I think they rather partly analogue of Lama guanicoe that can live in semideserts regions.

but yucca went exctinct on mainland north America according chapter apout Hawaiian flora. But it is not big loss - I think that arboreal pricky hear is enough to feed both oryxes and rapidocervuses withoutbuing eradicated by them.

Then I propose to live in chapter Prosopis glandulosa, commonly known as honey mesquite.

Okay. Fruits and foliage of this tree are edible for herbivores.

None of them, to be honest. The number 6 have the body type, but the head not match and lacks the hump. I thought that they would have the head like that of an oryx, with scimitar-like horns. With this head they look less as an oryx and more as a descendant of the cow. But it was a good effort.

Is possible to make some images by using the oryx and the giant eland (Taurotragus derbianus)? I think that the eland's body would be the closest for what we have in mind, and can have a more antilopine appearence rather than looking like a type of bull. Probably the hump would not appear, though. Sorry if I talking stupid things, I don't know how the neironet works.
Also, I discovered that Texas have a population of 9,000 Addax nasomaculatus. New Mexico also have some. This species can also have fertile hybrids with Oryx dammah. Maybe it goes extinct, but contributes to the humped oryx's genetic pool? Usually, the hybrid retains the oryx's horns, but have the fur color of the Addax. However, the humped oryx could develop slightly spiraled horns?
By this point, I have the suspicion that some of the scimitar oryxes living nowadays in areas of Texas aren't pureblood anymore. Some live in ranches together with O. gazellas and Addax, with hybrids looking similar to the sire, who can say if they already don't have a contaminated gene pool.

There are already a lot of hybrids of two oryx species: Oryx scimbok, they have interesting pink skin

So our new neocene animal can be descendant of hybrids of two species of oryx and addaxes.

I think that the de facto ancestor would be the O. dammah, but there would be some genes of O. gazella and Addax.

This is sad. Maybe you could use another large antelope. Does it know the Addax?

Finished the description of the microwolf's rival:

Microamphicyon (Ferocinomys predatorius)
Order: Rodentia
Family: Cricetidae
Habitat: Lowland tropical forests of the Panama Peninsula
The transition of the Holocene to the Neocene gave opportunities for species to evolve into new forms. The Chiriqui brown mouse (Scotinomys xerampelinus) is an example. This animal is the ancestor of the microamphicyon, a rodent that evolved to hunt in pairs. Inhabiting the lowland tropical forests of the Panama Peninsula, microamphicyon can kill prey as large as a rabbit and an opossum.
The microamphicyon has a head to body length ranging from 15 to 28 cm, while the tail ranges in length from 10 to 24 cm. The fur of dorsal areas is dark brown, with the ventral region being light buff. This creates a countershading in the lateral region. The hind feet are elongated, with reduced interdigital pads. The hypothenar pad is vestigial, while the thenar pad is elongated. The superior part of the feet is covered by silvery hair, while the ventral part is hairless with visible scales. The distal part of the tail is pale gray, with visible scales. The ears are medium-sized for a rodent of its size, covered with fur of the same color of the head, giving an homogeneous appearance. In a case of convergent evolution to the howling microwolf, microamphicyon developed sharp incisive teeth, with molars modified in carnassial-like way.
These rodents are totally predatory. Differently of microwolves, the microamphicyons only hunt vertebrates. Frogs, lizards, birds and other mammals are their main prey. Hunting in pairs, these animals are capable of bringing down adult rabbits.
Microamphicyon are monogamous, with females and males staying together for their entire life. They are extremely territorial, using both sonic and ultrasonic vocalizations to ward off rivals. Their vocalization also maintains packs of howling microwolves away. These rodents can breed throughout the year if conditions are suitable, with a female producing up to five litters a year. The gestation period is only 21 days, and litters can number up to 14, although seven is common. They reach sexual maturity in about five weeks. The maximum lifespan is three years, although most barely manage one.

Very cool description! But I don't like the name. May be microepicyon? If we decided to make a microworld analogue of big predators.

microepicyon

I think it is noy good variant. If i remember, epicyon was mostly opportunistic peredator that had several adaptations to eat remnants of other predator's food (for example, massive teeth shaped to crush the bones) and usually could chase smaller animals awayfrom theit food, but this animal is active hunter.
Maybe, we can call it "microcoyote"? Like its bei analogue, this animal lives in pairs and has concurention with "wolves".

The thing is that Ferocinomys is larger than the microwolf. I think that it would make more sense as an analogue of bear stealling food of pack predators.
