Tee of the Week


Hainosaurus I Choose You!....

This Hainosaurus boubker design is the latest to celebrate the discovery of this marine reptile!

The Mystery Dinosaur is proud to be working so closely with the paleontological team who are researching the fossil remains of the creature to unlock how this marine reptile lived!

All of our Hainosaurus merchandise is represented in our Hainosaurus Project by which a donation will be made to the research team each time you buy a Hainosaurus item! You can be a part of the science!

This design was fun to create and shows the Hainosaurus in a vintage pixel format with its level status and health bar just like in the retro games we played so long ago!

The Hainosaurus Project

In early 2022, fossil hunter Boubker Chaibi discovered an unusual fossil while digging in the phosphate basins near Oued Zem. It was a mosasaur premaxillary (nose/snout) bone, but instead of the broad snouted premaxillae seen in Mosasaurus and Prognathodon fossils that are common to the area, this snout was thin and didn’t have teeth at the tip. Boubker had discovered a tylosaur premaxilla, a bone from one of the largest and fiercest mosasaurs. The Hainosaurus.


The Mystery Dinosaur now works together with the paleontological team who helped to name the Hainosaurus and has created a line of merchandise that will let you show your love for this awesome marine reptile and its truly amazing discovery!

By purchasing the Hainosaurus merchandise a donation will be made to the team who are studying the Hainosaurus!


You will be helping to fund the science! You Rock!
