When did the first fossils of a marine reptile found and what is it?
The first fossils of a marine reptile, specifically an ichthyosaur, were found in 1811 in England by Mary Anning. Ichthyosaurs were large, dolphin-like creatures that lived during the Mesozoic Era, approximately 245 to 90 million years ago. These fossils provided important evidence for the existence of extinct reptiles in the oceans.
The dominant animal life during the Mesozoic Era was the dinosaur slash reptile True or False?
True. Dinosaurs were the dominant animal life during the Mesozoic Era, which is also known as the "Age of Dinosaurs." They were a diverse group of reptiles that existed for over 180 million years before going extinct.
What are facts about the mesozoic era?
Because the Diapsid reptiles (Dinosaurs in Particular) were seen as the dominant terrestrial life forms during that time, being both the Apex predators, and the largest herbivores. Odds were if you saw a vertebrate on land, it was a reptile. Additionally, during that time, reptiles also took to the sea in a far greater variety than seen today (and got quite large as well, Pliosaurs were likely Apex predators in the sea as well) That period was seen as a high point for reptiles - mammals now occupy most of the niches that reptiles did in the mesozoic. Additionally, when that phrase was made, Birds were not considered to be a highly derived/specialized reptile, further increasing the apparent contrast between reptile abundance now, and the much greater reptile abundance in the mesozoic. .... Although when that phrase was coined, the "proto-mammal" synapsids were considered to be reptiles, with the more advanced synapsids being called "mammal like reptiles" (they are no longer considered reptiles) So I must wonder why the term didn't originally refer to both the Permian and the Mesozoic. It must be the disparity in body forms - only during the mesozoic did reptiles take to the air, become apex predators at sea, and attain sizes unsurpassed by any other terrestrial life.
What is the meaning of marine organisms?
Marine organisms are living organisms that inhabit the oceans and other saltwater bodies. They encompass a wide range of species, from microscopic plankton to large marine mammals, and play crucial roles in marine ecosystems.
What is the largest group of marine organisms taken from the oceaN?
Phytoplankton are the largest group of marine organisms by biomass. These tiny plant-like organisms play a crucial role in the marine food web as they are the primary producers, converting sunlight into energy through photosynthesis. Their abundance and distribution support a wide variety of marine life, from zooplankton to large marine mammals.

What is a sea dinosaurs worst fear?

What did the pliosaurus evolve into?
Pliosaurus, a genus of large marine reptiles from the Jurassic period, did not evolve into any specific modern species. Instead, it is part of the broader group known as plesiosaurs, which were diverse marine reptiles that existed during the Mesozoic era. While pliosaurus itself did not have direct descendants, its lineage contributes to our understanding of marine reptile evolution. Today, its closest living relatives are birds, which share a common ancestor with reptiles.
What do kronosaurus eat?
Kronosaurus was a large marine reptile that lived during the Late Cretaceous period. It is believed to have primarily fed on other marine animals such as fish, squid, and smaller marine reptiles. Its large size and robust jaws suggest that it was a formidable predator in its oceanic environment.
What bug resembles a large mosquito in appearance?
