Robbery of Log Fossil described and considered geologic patrimony of Portugal

It was robbed to few days ago a log tree fossil of "Herdade da Coutada" in Vila Vélha de Ródão - Beira Baixa - Portugal with the following coordinates - 29S0618705/4393614
Description:
This fossil log, in excellent preservation state, weighs close to 15 tons and it measures 1,9 m of length for 98-84 cm of diameter and has a superior age at 5 million years. For the variation of the width along its axial axis, it is admitted that this fragment belonged to a tree with approximately 10 m of height in the main log.
Please if somebody recognizes or has information relatively to this situation that contacts the Portuguese authorities.
Thank you.

Martins,
It was sad to hear about this loss.
My only wonder is about your estimated weight of 15 tons. A cylinder with a diameter of 1 m and a lengt of 1,9 m. will have a volume of: 3,14 x 0,5 x 0,5 x 1,9 = approximately 1,5 cubic meters, With a density of 3,5-4 ( mainly quartz ? ) the estimated weight of the log would be no more than 5-6 tons and this can explain why it may have been possible to lift it on a truck and drive away.
Hopefully the specimen will be recovered and guarded in a museum.

Yes.... has logic the log have to the turn of 6 tons. I limited myself to transcribe the notice.
In the last times has people that robs old things as for example Pillories, statues, tiles, recorded stones etc. They arrive to the point of using detecting of metals in secret excavations to search old coins.
Thank you for your support.
