Dinomania Educates has announced a visit to Kingsdown School on Saturday, 24 July and tickets are on sale.
Would-be participants are warned that the model creatures are large and realistic, so there is a mild scare factor.
Dinomania travels around many schools, libraries and museums all over the UK teaching adults and children about dinosaurs.
A spokesperson said: "Once you're in, little ones can check out the mini-museum with real fossils, replicas and loads of fascinating facts.
"The exhibit includes items from all your favourite dinosaurs, like the T-rex, Spinosaurus, Triceratops, and Allosaurus along with other dinosaurs. If you don't know, just ask your kids.
"They even have some marine reptiles and prehistoric creatures. So there is plenty packed in to these two-hour slots, which will take place three times on the day."
Social distancing will be encouraged at all times, masks must be worn by everyone aged 11 or over unless Government guidance changes, there will be a 'no touching' rule and hand sanitisers will be available on entry and exit.
Ranger Chris and the rest of the Dinomania team say they had to work out the best way to deliver their theatre-style show but limit numbers to 100 tickets available per session to ensure social distancing was adhered to.
Sessions at the Swindon school will begin at 10am, 12.30pm and 3pm.
People attending will be able to speak with Chris and the other rangers from Dinomania, who will reveal everything about the amazing creatures.
Meet and greets will be available for the baby dinosaurs held by rangers., and there will be various workshops and activities.
All participants aged two and over will require a ticket, including adults, and these are priced at £15 per person.
