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