National Resources Wales have been made aware of a number of reports of anti-social behaviour over the weekend weekend, following the news of a new dinosaur footprint being discovered at the Bendricks Beach.
Lily Wilder, aged 4 made the discovery in January, with scientists now believing it could help establish how they walked.
Around 50 people attended the site near Barry – and although the majority of visitors left no trace of their visit, NRW has received reports of several people trying to remove rocks with sledgehammers and crow bars leading to several areas of the site being damaged.
The site where the fossil was discovered is a Site of Special Scientific Interest (SSSI) which contains geological features that require careful site management in order to protect and preserve them.
SSSI are protected under the Wildlife and Countryside Act and it is illegal to remove, damage or destroy rocks from this site without permission, which could lead to fines of up to £20,000.
National Resources Wales have also made residents aware that under the current Welsh Government guidelines you should only visit the site if you live locally to the area.
Anyone who sees any instances of anti-social behaviour on site is encouraged to report it to the Police via 101.
If you see anybody attempting to remove rocks please report it to NRW's incident hotline on 0300 065 3000.
