He’s only a freshman, and he’s loved paleontology a long time, so if that remains, likely geology or biology.
Hope e likes Montana!
If he is interested in Biology and maybe ultimately going to medicine, I would recommend Grove City College. Have a look this program :
I must warn you that they’re not an easy college to get through. They don’t teach fluff courses and they will not lower standards just to make students pass.
If he likes the outdoors, Berry College in NW GA would be hard to beat. I think it has the most acreage of any, mostly rolling hills and its own mountain ... “Berry’s campus, the world’s largest, includes a vast ecosystem of woodlands, meadows and streams and is home to unique opportunities for research, entrepreneurship, hands-on learning and recreation.” https://www.berry.edu/ . I think every student works on or off campus.
