A new home for BIG SARA

As seen on the BBC 1 documentary, ‘Attenborough and the Giant Sea Monster’, The Etches Collection has been home to the amazing Pliosaur skull for over a year now. But while this Sea Rex was ruling the oceans, who was the top dog on land?

Meet Big Sara, the newest and largest addition to The Etches Collection’s fossil family. Big Sara is an Allosaurus skeleton, cousin of the T-Rex, and top of the dinosaur food chain during the Kimmeridgian period. Spanning 10 metres long, this spectacular specimen has approximately 70% of her original bones intact, making Big Sara one of the most complete Allosaurus skeletons in the world. She was discovered in Wyoming in 2015 and is thought to have roamed the earth 150 million years ago during the upper Jurassic period - the very same time period that our Sea-Rex was dominating the seas!

Big Sara will be on loan to The Etches Collection for the next 2 years courtesy of The Richmond Group. Do not miss your chance to meet this incredible Allosaurus, she’ll be on display at The Etches Collection from Saturday 28th February 2026 in our Clore Room hall and is FREE to visit as part of your museum admission ticket. (Please Note:- Our Clore Room hall is used for school visits and hires and as such Big Sara won’t be accessible by the public during those times so we advise planning your visit to see Big Sara to coincide with when the hall is open - see below for the latest Big Sara viewing times)

Why not come and examine her for yourself, although looking at her 8 inch killer claws, I wouldn’t get too close…
