A team of technicians is hard at work sprucing up and repairing more than 20 dinosaurs from the Queensland Museum.

New skin, motors and teeth are being fitted to the animated dinosaurs that include brachiosaurs, a muttaburrasaurus and a T-rex.

Cherie McNair, head of exhibitions and creative services at the Queensland Museum, said the project had been quite a mission.

“Each dinosaur model has been renovated as close as possible to what we assume they looked like with the research our scientists have undertaken,” she said.

“The team have been making sure they move and make the noises they’re supposed too and are as lifelike as possible.

“Each model involves motorised parts, sensors, a skeletal frame and the skin components on the outside.

“They are a full-scale mechanical object so there has been quite a bit of maintenance required.”

New skin and clean teeth have been a priority for the technicians, who have come from around the state including the Railway Museum in Ipswich and Townsville.

“A lot of the skin needs to be replaced due to wear and tear from the public touching them and us moving them around,” Ms McNair said.

“Their teeth are being refurbished as well.”

The dinosaurs were disassembled and transported to Ipswich in shipping containers.

“It’s very odd to see dismembered body parts or in various stages of reassembly,” Ms McNair said.

“We didn’t want to scare anyone if we had them sticking out of the back of a truck.

“The dinosaurs have been in storage since last year so getting them out again has been quite a task.”

Visitors to the Railway Museum have been able to see the giant dinosaurs in many pieces during their renovation.

Dinosaur heads, feet and teeth have appeared sticking out of doors and windows.

“As people walk by near the storage areas they might have heard strange noises coming out,” Ms McNair said.

“They might have seen half a dinosaur as well … there’s been interesting reactions from kids and curiosity from adults.”

The crew working on the dinosaurs includes mechanical, electrical and design technicians.

“There’s been parts coming in from all over the world and it has been challenging for our team to resource many of the parts,” Ms McNair said.

“When we have them open to the public, we have an ongoing maintenance schedule for the dinosaurs like a car.”

The dinosaurs will return to the museum on June 21 as part of the Dinosaur Discovery: Lost Creatures of the Cretaceous exhibition.
