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.

Reading about the Myotis vivesi made me think of the oceanic bat.

Barracuda and lanternfish are exctinct because of planktonic disaster; euphausiids may also be affected. So you need to use convergent livebearers from "pirates of caribbean" chapter - pike livebearer and spear-mouth as barracuda and my "salinopoecilia affinis" as schooling fishes.

Would be possible for one of these new schooling fish to develop bioluminescence? Perhaps to communicate with each other wile they are in deep areas and later at night, when they come to close to the surface.

I don't think so, because bioluminescence is mainly deep sea animal feature, in upper layers of sea column other ways to communicate and hunt ate avaliable. But it can be some types of squid that lives in caribbean and uses bioluminescence to communicate.

Perhaps a tiny schooling squid? It could partially fill the niche of lanternfishes.

I "filtered" the species of rodents that can appear in the chapter besides Scotinomys teguina and Scotinomys xerampelinus.

Rheomys raptor (maybe a water shrew or tiny otter)
Zygodontomys brevicauda (maybe this one could be a tiny bear or a tiny panda, feeding mostly of green grass and occasional insect)
Transandinomys talamanca (could live in herds and move like a rabbit)
Peromyscus mexicanus (could live in groups like the guinea pig and maybe have tiny horns like the Ceratogaulus)
Orthogeomys cavator (maybe could form mounds in the ground that protect the entrance of their tunnels like tiny fortress)
Oligoryzomys fulvescens (mole like rodents feeding of roots and seeds. Opportunistics, they could use the protection of the tunnels made by the Orthogeomys)
Reithrodontomys mexicanus (nocturnal scansorial and acrobatic species, in the ground the microwolves will catch them)
Heteromys desmarestianus (can be a tiny porcupine)
Microsciurus alfari (can be the diurnal counterpart of the Reithrodontomys)
Oryzomys couesi (a semi-aquatic herbivorous species, like a tiny nutria. It could make nests with twigs and grass near water)

What do you think?

I've made the changes in the bestiary.

I coloured in blue colour the species we need to choose or throw out.

My suggestions of species we can throw out are crossed out. Are you agree whit my choice?

But we can leave a maximum of 19 species, we need to throw out someone else, although it's a pity, I would like to leave them all. Who else from those highlighted in blue do you propose to remove from the chapter?

The Octopoteuthis danae, which already have photophores. The common name could be firefly squid, because it's small and luminous.

Eneoptera surinamensis (we already have one Orthoptera with the Stilpnochlora). Maybe Marmosa mexicana, Transandinomys talamancae (we already have other two "herd" animals, besides Peromyscus could be the one moving like a rabbit, it would turn them more in a tiny deer), Megasoma elephas and Limax maximus. I'm very reluctant of removing these though, they are very interesting species.

I wanted to have marsupial species in the chapter. Don't forget, we can make subspecies.
We can make marsupial tiny bear ( it
can form mounds in the ground that protect the entrance of their tunnels like tiny fortress), And marsupial tiny panda living in little groups of one male and some females instead of
Zygodontomys brevicauda. Let's cross out it.
Microvolves will eat micropandas too, and fight with microbears.

Let's better change them by marsupial tiny bears.

We can still use the crossed out species in the chapter about astrapotherium like pecarry living in the rainy forrest of Panama on the coast of Carribbean sea and up north to the Mexican southern forests.

Then one subspecies will be more carnivorous, while the other would have preference for plants.

In this chapter we could mention the impact of the peccaries in the small species of these forests.

For example peccary manure can become a habitat for earthworms and some other species that eat it and become food for insectivorous rodents and birds, as in the African chapter 58. Workers of decomposition, also insectivorous birds can eat parasites of pecarry. What the other impact do you mean?

I think there can be other forms of impact: the trails will be overgrown with specific vegetation: grass, shrubs (may be with berries). Large animals can create fringes in the forest. Perhaps we do not take into account some other important forms of impact of big animals in the forest on small animals.

They can crush smaller animals and destroy their hidding places. By the way, there is monster in the Guarani folklore called Ao ao that is a giant carnivorous peccary. Do you think that we could use this name for a species?

I know that we talked about a bone crushing dog filling the niche of hyenas living in Patagonia and Pampas, but what do you think if we replace it with a scavenger pig or peccary? We could use the name of the Ao ao. Maybe rather than living in the South, it could live in the cerrado and Gran Chaco.

I think that it works, besides the bone crushing dog would be far more predatory than the peccary, who would be more opportunist.
