Not all the time. It rotates.
I go there every 2-3 months and I'd say they rotate displays within that time frame. You'd have to call to see the next time it will be back.
The one we went to was only on for a little while. I don't know if they have one regularly but if you look at their website you can see what they have going on.
The exhibits change constantly. Check on the website to see what's on display
Sometimes. You better call ahead and make sure
I do not think so at this time
No they do not have a dinosaur exhibit the National History museum in Manhattan should have one
I dont remember seeing one when i went in February 2018. Just give them a call they are really nice there
