We love your gem mining kits. Interesting specimens in each one. It’s a great backyard activity for the kids!

I'm glad I got the opportunity to purchase Rex Appeal2 from Tyrannostorus. The condition of the book was immaculate out of the package and matched the online description. Although there was issues with shipping that lead to the book arriving late, the store owner made efforts to secure an extra surprise poster to be sent with the book. This made up for any inconveniences that occured. In my experience, Tyrannostorus will do whatever they can to fix mistakes and deliver extra to satisfy customers.

This was awesome! As a big dinosaur and shark person, to be able to have even a piece of Megalodon is super cool! Tricky bit is that it’s a gift for someone else and I don’t have one haha. Delivered super quick and I’ve been watching you guys online on Instagram and love what you do. Would love to eventually have a megalodon tooth of my own. I have a couple of prehistoric shark teeth in my collection. The person I’m giving the gift to is going to absolutely love it.

Wonderful experience. Rapid shipping and product is as described.

Love it!!

Decent product, decent shipping

Purchasing a replica shark tooth for grandson's birthday. I had several questions about this item, and my questions were answered promptly. I am completely satisfied with this purchase and my transaction and would highly recommend this merchant!

All of the science classes we have gone to have been outstanding.

We love Tyrannostorus!

My son's reward for doing well in school is your classes. Learning is too much fun😊

Class was awesome

Fun class, friendly and knowledgeable staff

We had a blast at the Palentology class! The lecture portion was age appropriate and even the adults learned a lot. My children loved digging for fossils and the instructors were great about answering all the questions we had. We are looking forward to coming back soon!
