Hevisaurus are a Finnish heavy metal band that was formed in 2009 with music aimed at children.

[15] A video of the audition was released on the Spain's Got Talent Youtube channel, with the group receiving three yes' and being able to move on to the next round.

According to legend, five dinosaur eggs made from metal survived the mass extinction some 65 million years ago in the mountain of wizards.

A giant lightning bolt hit the ground and simultaneously created ash and revealed the eggs.

Due to the nature of their music being targeted at children, the lyrics are often educational such as Tahdon Maitoo, a song from Hevisaurus' album Räyh!, which celebrates the benefits of the nutritious calcium-rich goodness of milk.

[19] At the beginning of 2011, Mirka Rantanen, the drummer and one of the founding members, fell into a dispute between their record label Sony Music Entertainment about the copyrights and trademarks of the characters.

As a result, Rantanen formed a competing band called “Sauruxet”, with the people who played in the Hevisaurus live set-up.
