four animals from the permian that i drew for three reasons, one, to practice, two, because i was bored, and three, because i wanted to draw some prehistoric animals. these animals are: -Ophiacodon -Eryops -Mesosaurus -Arthropleura (tecnically appeared in the carboniferous, but survived into the early permian) ------ cuatro animales del pérmico que dibuje por tres razones, una, para practicar, dos, porque estaba aburrido, y tres, porque quería dibujar algunos animales prehistóricos. estos animales son: Ophiacodon -Eryops -Mesosaurus -Arthropleura (técnicamente apareció en el carbonífero, pero sobrevivió hasta el pérmico temprano

Commission for a person from ych.commishes of a lovely hatzegopteryx! This is the first time in a while I drew a pterosaur, but I'm quite satisfied with the result.

Some Definitions

Dinosaur: the Most Recent common ancestor of Megalosaurus and Iguanodon, and all of that ancestor’s descendants. This includes birds. It does not include pterodactyls. Or cockroaches. Or sharks. Or lizards. Or tuatara. Or mammoths. Or Dimetrodon. Or-

Prehistoric Life: any living thing that existed prior to the development of agriculture. Many things around today, including people, have prehistoric counterparts.

Extinct Life: any living thing that is now extinct, ie, no longer around. This includes things that have gone extinct since agriculture.

Lizard: The Most Recent Common ancestor of modern Iguanas and Worm Lizards, and all of that ancestor’s descendants. This includes snakes. This is a completely separate group from dinosaurs, defined above. They are utterly separate.

Reptile: any animal closer to living lizards than to mammals. This includes all birds, as well as other dinosaurs, turtles, crocodilians, and tuatara. It does not include Dimetrodon.

Synapsid: any animal closer to living mammals than to lizards. This is where Dimetrodon is. Also humans. And mammoths. All mammals are synapsids.

Tada! Now you know!

This is pretty cool! While there are thousands of this species in captivity in crocodile farms, wild populations number in the hundreds at best. Moreover captive animals are often hybridized, not pure, and so many genetic lines have been lost for conservation purposes. And captive and wild populations have diverged enough that the loss of wild lines entirely would be a devastating blow to the species as a whole.

The success of this nest is a hopeful sign for the Siamese crocodile; here's to better news in the future.

Brontosaurus yahnahpin/Apatosaurus yahnahpin – Thundering Deceptive Skytower

Brontosaurus is the extinct genus of herbivorous sauropod dinosaur that lived in present-day United States during the Late Jurassic period. The third species of Brontosaurus is Brontosaurus yahnahpin (yahnahpin-wearing deceptive lizard), and it was described by American paleontologists James Filla and Pat Redman in 1994.

Animal of the Day!

Pinta Island Giant Tortoise (Chelonoidis abingdonii)

(Photo by Santiago Piedra)

Extinction Date- 2012

Habitat- Pinta Island

Size (Weight/Length)- 180 kg; 1.8 m

Diet- Cacti; Grasses; Berries; Leaves

Cool Facts- The Pinta Island giant tortoise was only found on Ecuador’s Pinta Island in the Galapagos archipelago. These gentle giants would sleep up to 16 hours a day and spend the rest of their time eating. They would feast on cactus pads and fruit along with coarse grasses. Pinta Island giant tortoises were the top herbivore of Pinta Island and played an important part in dispersing cacti seeds. When explorers and whalers first discovered the Galapagos, they released the slow moving and long living giant tortoises made the perfect meal and killed them in the thousands. Goats were later brought to Pinta Island and destroyed the vegetation the tortoises needed. The last Pinta Island giant tortoise, Lonesome George, was luckily saved and was an estimated 100 years old when he passed away on June 24, 2012. Today, every giant tortoise species that remains in the Galapagos are either endangered or critically endangered. Off site breeding efforts in zoos worldwide has boosted their populations considerably although it’s been a very, very slow process.

Rating- 13/10 (Possible hybrid tortoises remain in zoos today.)

Could you put him in the show ENA?

Yeah I know this poll is a little apex predator heavy, but to be frank, most sea creatures (living and extinct) would amount to nothing more than fish/whale/ichthyosaur/shark, etc. fodder and that would not make for a fun poll.

Oh I haven’t posted in 9 months Oopsies

Here’s an art dump to make up for it

Though I can’t post everything I’ve drawn in the last 9 months, this is a bit of a highlight reel :)
