[US] Is there a way to check if a website is legit or if it’s a fake? https://www.indianadinosaurmuseum.org/

Concerns stem from receiving an email using a .com address while the museum's website is a .org, and observations that the website lacks current job listings, staff names, or easily findable phone numbers.
