Welcome to Cairngorms Jurassic Park!
They were the star of this year's Halloween celebrations in Grantown.
This raw, awesome foursome roared its way through the Strathspey capital chasing away any evil spirit crazy enough to challenge them.
Photographer Heather Fraser told the Strathy: "Reflecting on how popular these four were last night, I propose we ask them to come forward and identify themselves, and be awarded the Keys to the Town for their commitment to public service!
"Grantown-on-Spey hasn't laughed so much in a long time!"
The dynamic dinos took in most of the town and even headed into the community centre at one stage, to enjoy the daunting delights of the Haunted House for a while.
Grantown YMCA Community Centre posted their thanks to everyone who dared to enter the chamber:
"We were amazed by the 500-plus brave souls who joined us.
"Together, we raised an incredible £366.20 for a fantastic cause. Your support made it a spooktacular success, and we can't wait to see you at our Santa's grotto in December.
"Thanks again to all our fearless guests!"
There were special thanks for the team who had set it all up and their volunteers on the night who had ensured the spirits were well and truly vanquished.
The heroes were Claire Thom and Hamish Thom, Fiona Rodgers, Karen O’Connor, Daphie Ritchie, Jason Gordon
and Stewart Mackie.
As for the dancing dinosaurs, Heather Fraser said: "Whoever they were, they were hilarious and put so many smiles on so many faces!"
