The animal you are describing is likely the black-maned version of the domestic horse, specifically a breed such as the Mustang or an Arabian horse. However, if you're referring to a wild animal, it could resemble a coyote, but there are no direct wild animals that fit that exact description. In general, horses can have a variety of coat colors and mane styles that might evoke that image.
they are black sometimes brownThe color coyote varies from brownish gray to grayish brown, depending on the manufacturer.
No, they are basically a tawny, brown animal.
Usually hammer head shaped if they are black or an arrow shape if brown
No there is only dark brown and light brown hair.
There are more black bears than brown/grizzlies, but the brown is a much larger, more powerful animal on average, and will kill black bears.
I dont think any animal stops at a state boundary. I never ran a coyote that said, " better stop here".

The spider you are referring to is likely the brown recluse spider, which is known for its brown coloration and dark violin-shaped marking on its back.
A brown beetle with black spots typically has a shiny, oval-shaped body with six legs and antennae. The brown color may vary in shade, and the black spots are usually scattered across its back.
The color of the coyote's coat varies from grayish brown to yellowish gray on the upper parts, while the throat and belly tend to have a buff or white color. The forelegs, sides of the head, muzzle and feet are reddish brown. The back has tawn-colored underfur and long, black-tipped guard hairs that form a black dorsal stripe and a dark cross on the shoulder area.
No, I believe it is the Marine's.
No. It's more broad & kind of wedge-shaped. Black Rats have a very narrow snout
