here's today's #Paleostream sketches!!! today we drew Cretoxyrhina, Barinasuchus, Clidastes, Hypuronector

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.

Island ecosystems are always more vulnerable than those on larger continents. Less space means fewer resources, which leads to each species having a smaller population. For endemic species that can't fly or otherwise get to another island or mainland, once that one island's ecology is disrupted significantly enough, the risk of extinction becomes very real.

Sombrero Island is no exception, having been completely deforested and torn up for mining. Invasive mice put further pressure on native species. With the mice eradicated, native plants can once again thrive, and the Sombrero ground lizard is less likely to see its eggs or young eaten by hungry mice, and its population has risen from fewer than 100 individuals in 2018 to over 1600 today.

This is yet another example where removing invasive species and restoring habitat with and for native ones can help an ecosystem and its inhabitants recover. The more biodiversity we preserve on our planet, even in these seemingly tiny, isolated places, the better equipped all of us will be to weather the years to come.

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!

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.)

Animal of the Day for December 30: Palaeophis

A genus of aquatic snakes that evolved during the Late Cretaceous, Palaeophis would survive the K/PG mass extinction and become one of the dominant predators in shallow seas, much like Boids and Madtsoiids did inland. They are also among the largest snakes with the largest species, Palaeophis colossaeus, reaching an estimated 40 feet in length.

Unfortunately (or fortunately, if you have ophidiophobia) these animals would ultimately die out due to global cooling, decreasing sea levels and competition with early whales.

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.
