Hi Sherry! The Museum of Ancient Life is one of 5 venues at Thanksgiving Point! So admission to the Museum of Ancient Life only includes that venue, or you can look into an Explorer Pass which includes one day admission to all 5 venues!
Going to Thanksgiving Point is free. As long as you don't go inside any of the locations that require tickets, you can walk around the place without paying a penny. Tickets to the locations, on the other hand, do cost money. So keep that in mind.
Thanksgiving Point is the name of the general area that contains a lot of different places. A ticket to the Dinosaur Museum gets you into the Dinosaur Museum but not the other places (e.g. Butterfly Exhibit). Think of it like a ticket to Magic Kingdom. That ticket gets you into "Disney World", but what it really means is you can get into Magic Kingdom but not Epcot, Hollywood Studios, etc. There are tickets you can buy that get you into multiple attractions at Thanksgiving Point, but a ticket to the Dinosaur Museum is only for that attraction.
I suggest you go to their web site. They have a fee for a single attraction and a different fee for multiple attractions.
