Fossil Atlas country guide
Dinosaur fossils in Morocco
Morocco is central to the modern Spinosaurus story. The Kem Kem beds in the southeast preserve Cretaceous river-system fossils, including Spinosaurus and other large vertebrates, and Fossil Atlas uses this page to connect those records to the animal profile and map.

How to read these country pages
Country pages are search entry points into Fossil Atlas, not national fossil encyclopedias.
02 / Evidence
Modern records, not ancient ranges
Country names describe where fossils are found or reported today. They do not reconstruct where animals lived in deep time.

The region
Sahara desert, Cretaceous river
During the Cretaceous, Morocco was not a desert. The Kem Kem region was a vast river system — wide channels, sandbars, mangrove swamps, and tidal flats where fresh water met a shallow Cretaceous sea. This environment supported an extraordinary concentration of large fish, crocodilians, and predatory dinosaurs. Today the fossil remains weather out of sandstone cliffs, collected by local people and studied by international paleontologists.
The ecosystem
A river of giants
The Kem Kem ecosystem is unusual because large predators are especially prominent in the known fossil record. Spinosaurus, other large theropods, crocodyliforms, and large fish are often discussed together in this context. The relative scarcity of herbivorous dinosaur material suggests that aquatic prey and river habitats were central to how this ecosystem worked, though the exact food web is still debated.
The fossil trade
Commerce and science
Moroccan fossils are widely sold in markets and online, which creates both opportunities and challenges for science. Commercial collecting can bring important material to attention, but fossils sold without reliable locality and formation data lose much of their scientific value. For Fossil Atlas, that provenance problem is exactly why mapped records need clear caveats and source context.

FAQ
Common questions about dinosaur fossils in Morocco
Where in Morocco are dinosaur fossils found?
The best-known Moroccan dinosaur records on Fossil Atlas come from the Kem Kem beds in the southeastern part of the country near the Algerian border. This region preserves a Cretaceous river system associated with Spinosaurus and other large vertebrates. Morocco also has important fossil-bearing regions outside the dinosaur-focused pages, including phosphate basins that are especially known for marine reptiles and fish.
What is the Kem Kem Group?
The Kem Kem Group is a geological unit of Late Cretaceous age (roughly 100–94 million years ago) exposed in southeastern Morocco. It was deposited by a vast river system that flowed across what is now the Sahara Desert. The Kem Kem is famous for its high concentration of large predatory dinosaur fossils — Spinosaurus, Carcharodontosaurus, and huge crocodyliforms — representing a predator-dominated ecosystem that has few modern analogues.
What dinosaurs lived in Morocco?
Morocco's best-known dinosaur on Fossil Atlas is Spinosaurus aegyptiacus, a large semi-aquatic theropod. Other Moroccan dinosaur names often discussed in the literature include Carcharodontosaurus, Ouranosaurus, and several sauropods. The Kem Kem beds are especially notable because large predatory animals are prominent in the known fossil assemblage, which raises interesting questions about ancient river food webs.
Are there marine reptiles found in Morocco too?
Yes. Morocco's phosphate deposits, especially around Khouribga, are well known for Late Cretaceous marine fossils, including mosasaurs, plesiosaurs, marine turtles, sharks, and fish. Those marine beds are a different fossil context from the terrestrial and river-associated dinosaur records highlighted on this page.

Caveat
What this page does not claim
This page describes selected fossil-bearing regions in Morocco based on published literature and the current Fossil Atlas dataset. It is not an exhaustive directory of every Moroccan fossil site. Fossil maps on linked pages show modern discovery locations, not ancient habitat reconstructions.
Information about the commercial fossil trade is included for context and does not constitute endorsement. Scientists recommend that significant specimens be documented and deposited in recognized institutions whenever possible.
