Nyasasaurus (meaning "Lake Nyasa lizard") is an extinct genus of avemetatarsalian archosaur from the putatively Middle Triassic Manda Formation of Tanzania that may be the earliest known dinosaur. The type species Nyasasaurus parringtoni was first described in 1956 in the doctoral thesis of English paleontologist Alan J. Charig , but it was not ...
Most lizard species and some snake species are insectivores. The remaining snake species, tuataras, and amphisbaenians, are carnivores. While some snake species are generalist, others eat a narrow range of prey - for example, Salvadora only eat lizards. [33] The remaining lizards are omnivores and can consume plants or insects. The broad ...
The oldest undisputed lizards date to the Middle Jurassic, from remains found In Europe, Asia and North Africa. [54] Lizard morphological and ecological diversity substantially increased over the course of the Cretaceous. [55] In the Palaeogene, lizard body sizes in North America peaked during the middle of the period. [56]
The largest known land lizard is probably Megalania (Varanus priscus) at 7 m (23 ft) in length. [280] As extant relatives, Megalania could have been venomous and in that case this lizard was also the largest venomous vertebrate ever evolved. [281] However, maximum size of this animal is subject to debate. [282]
Argentinosaurus (meaning "lizard from Argentina") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution ...
