Spinosaurus aegyptiacus holds the distinction of being the largest predatory dinosaur ever discovered — longer than Tyrannosaurus rex, heavier than most things that have ever walked the Earth. What makes it genuinely unusual is what it chose to do with that size: get in the water.

Landmark studies published in 2014 and 2020 confirmed Spinosaurus as highly adapted to aquatic life — dense bones for buoyancy control, paddle-like feet, nostrils positioned high on a crocodyliform skull, and a tail shaped for propulsion through water. It inhabited the river systems and coastal waterways of prehistoric North Africa, hunting primarily large fish including the giant sawfish Onchopristis. It is the only known dinosaur with confirmed semi-aquatic adaptations.

Our sea monster fossils are not factory produced. Each tooth has spent between 15 and 100 million years underground before arriving at your door — minor surface variations, natural color differences, and the occasional imperfection are evidence of that journey, not departures from it. We hand select every specimen for quality and character, but nature had a few million years of input before we did.

Orders ship within 3-5 business days and arrive within 5-10 business days depending on your location.

If for any reason you're not satisfied, please reach out to us within 7 days of your product's delivery and we'll make it right.
