FIELD GUIDE

The story

The biggest dinosaur at Field Station: Dinosaurs is now a burned steel frame, and the park says it is beyond repair.

The park sits at 2999 North Rock Road in Derby, Kansas. It opened in May 2018 on 14 acres with 44 life-size animatronic dinosaurs, a lake and a quarry, at a cost of $6.5 million that the Associated Press said was met with private financing and sales-tax revenue bonds from the City of Derby. The park now advertises over 40 true-to-size dinosaurs, with a Field Note at each one written in partnership with the Elevation Science Institute.

Its Sauroposeidon, a long-necked plant-eater, was among the largest. KSN reported it as 40 feet tall, 93 feet long and nearly 60 tons, and called it the longest animatronic dinosaur ever built. That superlative is KSN's own wording; KSNW later called it 'one of the largest', and a syndicated report put the length at roughly 100 feet. On a Saturday evening in late April 2026, the Derby Fire Department said, lightning ignited the model; fire burned away everything except the metal frame. Firefighters stopped it spreading, no injuries were reported, and the park opened the next day.

The park's operations manager first said a full replacement would cost hundreds of thousands of dollars, and raised the idea of leaving the skeleton on show. On 5 October 2026 KSNW reported that the park had written on Facebook that the frame is "too weak and brittle to support the structure", and that the dinosaur will be taken down after Dinosaurs After Dark ends on 30 October.

The park's website lists a new exhibit for the fall event, The Ghost of Sauroposeidon, without saying what it is.
