Gallardosaurus
Gallardosaurus was a short-necked, big-headed marine reptile that swam in warm seas near Cuba 160 million years ago. It was a pliosaur, a type of plesiosaur with a huge skull and strong jaws for catching fish.12

Gallardosaurus is known from only one partial skull and a few neck bones. The tip of the snout and the back of the lower jaw are missing.1
The bones were found inside a hard rock called a concretion, which helped preserve them in three dimensions.1
The individual was probably not fully grown when it died, because some of its vertebrae were not fused together.1
Gallardosaurus lived in a shallow sea only about 10 to 12 metres (33 to 39 feet) deep. Oysters and algae grew on the seafloor.1
It shared its home with ichthyosaurs, a marine turtle called Notoemys oxfordiensis, and another plesiosaur named Vinialesaurus caroli.1
Scientists think Gallardosaurus may have migrated across the Caribbean Seaway each season, following the fish it hunted.1
The first fossil was discovered in 1946 by a Cuban farmer named Juan Gallardo. It was not fully studied until many years later.1
ຄຳຖາມທີ່ຖືກຖາມຫຼາຍທີ່ສຸດກ່ຽວກັບ Gallardosaurus
?How big was Gallardosaurus?
No complete skeleton has been found, so its exact size is unknown. Based on the partial skull and neck bones, it was probably a medium-sized pliosaur, but scientists do not have enough fossils to give a reliable length or weight.12
?What did Gallardosaurus eat?
It was a carnivore that likely ate fish. Scientists think it was an active predator that hunted nectonic (swimming) fish in the warm Caribbean Seaway.12

- The only known fossil was found in 1946 by Cuban farmer Juan Gallardo near Viñales, Cuba. It was first thought to be a species of Pliosaurus or Peloneustes, but in 2009 paleontologist Zulma Gasparini named it a new genus, Gallardosaurus.12
- ຍັງຖົກຖຽງກັນຢູ່
- Scientists are not sure exactly how big Gallardosaurus grew, because only a partial skull and a few vertebrae have been found.1
