Nearly two years here, time for a new #introduction post: I go by Dynamognathus/Dynamoterror, I like drawing, wildlife, natural history, drawing the natural history of wildlife, gardening, spec-evo, and my dear boyfriend @seismic-shrimp.bsky.social (who does amazing art and who you should follow).
Colored-pencil drawing of a cube-shaped ecosystem diorama, showcasing a slice of a steep pond bank in early Pliocene Tennessee wherein all 10 known mole and shrew species are shown, in addition to a turtle and a few birds. Black-and-white pencil sketch of a scene in an estuary channel on the edge of the Caspian Sea, showing a massive Beluga Sturgeon curling upwards beneath the surface of the water. Its mouth is extended as its head approaches one of two young tiger cubs, swimming on the surface behind their mother. The distant river banks are covered in dense, tall reeds. Colored pencil drawings of two fictional tree species from an alternate-prehistory version of the Triassic. One is a slender, roughly cone-shaped Peltaspermale with four-lobed leaves and drooping branches. The other is a tall and columnar Ginkgoale with a wide-spreading crown and small leaves. The leaves and reproductive structures of each species are drawn below them up-close. Colored-pencil drawing of a Megalonyx rearing up in front view with arms outstretched, amongst a bunch of tall grass, with the evening sky in the background being the colors of the bisexual flag.

A paper was just published that looks at the genomes of all Gibbons, forming a full phylogeny and demographic history and finding the enigmatic Junzi imperialis to be the sister species of Nomascus hainanus (Junzi is a synonym of Nomascus)!!!! www.cell.com/cell/abstrac... #primates #science #gibbons
Genome sequences of extant and extinct gibbons reveal their phylogeny, demographic history, and conservation status
This study presents a comprehensive evolutionary history of gibbons by resolving their contentious phylogeny, reclassifying an extinct species with ancient DNA, and identifying a structural variant po...

Colored sketch of the newly-validated Nanotyrannus lancensis, though it’s not having a good time. This baby has found itself grappled by a particularly ambitious Didelphodon, after wandering a little too far from home. #backinhell #paleoart #sciart #cretaceous
Colored-pencil drawing of a Didelphodon in a sit-up position, grabbing onto a fluffy baby Nanotyrannus with both hands and one of its feet while its jaws completely envelop and crush the back of the small theropod’s skull. The Didelphodon is overall very dark brown in color, while the baby Nanotyrannus is a mix of olive tan and orange with thin dorsal stripes.

A quick doodle for the final day of #GarWeek, a large melanistic Alligator Gar cruises underneath an oblivious Ocelot somewhere in the bayous of Louisiana. A scene that may have happened several times in the past, and may continue to occur if both species are valued and protected. #wildlife #sciart
Black-and-white pencil sketch of a melanistic Alligator Gar swimming underneath a much smaller Ocelot that’s paddling on the surface above it.

Foggy morning in Late Pleistocene Patagonia.

#Art #SciArt #artbyjulio
A scene depicting the Patagonian scrubland in the early morning, dotted with araucarias and framed by foggy mountains in the background. A pair of Macrauchenia, four guanacos and a patagonian mara are seen among the grass. A Megatherium walks by further away and a crested caracara flies over the scene.

Tonight’s flocking #Paleostream sketches (it’s been a hot minute): Nanotyrannus in the woods, Pteranodon over Protosphyraena, Phosphorosaurus + sturgeon lunch, and Helicoprion. #paleoart #sciart #cretaceous #permian #backinhell
Four black-and-white pencil sketches of prehistoric animals, arranged in four quadrants on a piece of paper. In the top left is a Nanotyrannus, facing angled away from the viewer between several very large trees. In the top right is a female Pteranodon flying low over the water of the open ocean, looking at a large Protosphyraena fish swimming at the surface. In the bottom left is a Phosphorosaurus swimming with a particularly large sturgeon writhing in its jaws. In the bottom right is an up-close face of Helicoprion in side view, showcasing small scars and sensory pores as it swims upwards.

I don't post it here much, but I love photographing wildlife nearly as much as I love drawing it. Here, a Chipping Sparrow borb rests atop the neighbor's fence. #wildlife #bird #photography
A photograph of a small Chipping Sparrow sitting on the top of a tall, pale-brown wooden fence, facing towards the right. Behind it is a blurry green background of the woods. The sparrow is a deeper brown than the fence, with bars and stripes on its wings and a reddish top of its head.

On the coast of Pliocene California, a Homotherium pounces upon a newborn Herpetocetus morrowi. These are Cetotheres, small baleen whales that thrived during the Miocene/Pliocene. For the sabertooth, such a tiny calf so close to shore is a rare treat. #paleoart #sciart #pliocene #california
Black-and-white pencil drawing of a predation scene in the shallow coastal waters of California during the Pliocene. Near a large rock, a mother Herpetocetus morrowi (four-meter-long baleen whale) rests at the surface with her newborn calf balancing on her back. She has just begun to curve downwards in a dive, as a relatively large Homotherium sabertooth-cat is leaping towards her tiny calf with its front paws outstretched. The large cat had been crouched atop the nearby rock. In the distance, a massive cumulus cloud sits just above the surface of the open ocean. On the seafloor below are two small sea urchins, and on the base of the large rock near the seafloor is a Pacific Rock Crab.

Quick finger-painting of a wild horse, using water, red clay, and a sidewalk. There were many wild horses here throughout most of the Cenozoic up until the very recent past, but now only scattered fossils and subfossils remain. Inspired by @nicodelort.bsky.social.

October’s #NearbyNature2025 post is of Ctenus hibernalis, a harmless species of wandering spider found almost exclusively in Alabama. They are comparable in size to large wolf and fishing spiders, but are way more secretive than either (I’ve only ever found three). #sciart #wildlife #alabama
A colored-pencil drawing of the wandering spider Ctenus hibernalis in dorsal view. It is overall dark brown, with a pale dorsal stripe on both the cephalothorax and the abdomen. Its legs are posed asymmetrically, in a relatively active pose.

A partial recon of the new North American Pleistocene bovid Speleotherium logani. This guy is one of the few NA megafauna from this time described in the last century. Also showing that we still don't have a complete knowledge of the megafauna of Pleistocene NA #paleoart #sciart

Quick sketches of a concept I just had for my personal spec-evo project, a Kerguelen “Panther” that’s actually a cat-convergent Tritylodont. It’d be one of the apex predators of the Kerguelen landmass during the Holocene, sometimes attacking adult “dragons”. All of this is a long-term WIP. #specevo
Three rough black-and-white pencil sketches on lined paper. The top one is a skull of a fictional, big-cat-convergent Tritylodont in side-view. It has two large upper incisors that sit on either side of two large lower incisors, and huge, blade-like rear teeth. The sketch below it is a life drawing of the Tritylodont in side view, it looks lot like a nondescript big cat. The sketch below that is of a dead individual between two stick-figure humans, one holding its head up and holding a gun in the other hand, and the other human holding up its tail. A rough black-and-white pencil sketch on lined paper, showing a Kerguelen panther mid-leap and latched onto the neck of a larger, dragon-like Thyreophoran, which is rearing up in furious shock.

Quick sketch (will likely add to it later) of the Toronto Subway Deer, formerly Torontoceros hypogaeus. A new paper has analyzed dna from the only known specimen (fragment of skull + antlers), and it’s a member of Odocoileus! Likely the closest relative of Mule Deer. #pleistocene #canada #sciart
Very rough black-and-white pencil sketch on a piece of paper, depicting the Toronto Subway Deer as a Mule-deer-like member of Odocoileus. It’s staring directly at the viewer, with a relatively thick neck and wide-spanning antlers. The outline of the actual specimen (a skull cap with broken antlers attached) is visible within the life reconstruction. The same sketch as in the other image, this time digitally placed over a photo of the specimen and next to a black human silhouette + a two-meter-tall scale bar.
