A 120-year-old crocodile discovered under the floorboards of a school classroom in Rhondda Cynon Taf has gone on display.
The remains of the giant saltwater crocodile were found by workmen in June 2019 and have been meticulously conserved.
Pupils at Ysgol Gynradd Gymraeg Bodringallt in Pentre, arrived at school on Wednesday to view the new display after restoration of the skeleton was completed over Christmas.
Rhondda Cynon Taf Council worked with Pure Conservation, a Welsh company with expertise in conservation for heritage collections, to restore the remains.
After inspecting the crocodile's bones, Pure Conservation believes it dates it back to before the 1900s.
A story about a crocodile being associated with the school has been told across many generations, with the tale describing a local person who served in the First World War bringing back the body of a crocodile as a souvenir for the school.
It is thought that the crocodile was put on display but then hidden beneath the floorboards to protect it during later times of conflict.
Conservator Dr Victoria Purewal and artist Annette Marie Townsend, who specialises in natural history, worked on safely restoring the crocodile from September 2019 to December 2021.
Specialists said the crocodile had suffered significant damage having been left unprotected for potentially 100 years, with its entire underside missing, along with its feet and the base of its tail.
Its teeth had also fallen out and its general condition was very poor.
The entire body was initially frozen to remove pests and was tested for dangerous materials, before the crocodile was wet cleaned.
The process involved meticulously dry cleaning the crocodile's entire body, with separate pieces vacuumed to remove dirt, cobwebs and soil.
The bones were cleaned in a slow process taking several attempts, and the loose teeth were reconciled with the sockets.
The crocodile and its supporting mould were completed just before Christmas and were put on display at the school on the evening of January 11, along with a box holding several sections of loose materials and three bones.
Rhondda Cynon Taf cabinet member for education and inclusion services, Councillor Joy Rosser described the discovery as "absolutely incredible".
She said: "It was the last thing workmen thought they'd find underneath a classroom.
"It was fantastic to see the excited look on pupils' faces when they saw the crocodile on display.
"I'm sure it will become a cherished part of the school going forward - representing a one-of-a-kind, real piece of local history which can be enjoyed by pupils and staff members for generations to come."
