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.

Another concept-sketch for my personal spec-evo project: a small mammal, after weeks drifting at sea, looks up at its strange new neighbor on the shore of the Kerguelen landmass. At some point in the Paleocene, I’m planning on an endemic radiation of Xenarthrans taking hold. #specevo #xenarthra

A rough black-and-white pencil sketch of a small, rat-like Xenarthran mammal sitting and looking up at a very tall, early Penguin. They are on a relatively flat coast with a few low-lying plants around them.

Though other subspecies of green alar (also just called alar) can get quite large, the Seridic alar is the smallest member of not only the species but the genus overall. It is generally believed living alongside the only living species of Ardeanax (the ba'khar) contributes to this restriction.

Preview of my latest #paleoart piece: a baby bison flees the deadliest predator of Ice Age Europe. Harrowing, harrowing stuff.

Quick drawing of a speculative, but plausibly real, bird. New-World Warblers in the family Parulidae readily hybridize, and this is what I imagine a cross between a Magnolia Warbler and a Northern Parula might look like. #bird #warblers #wildlife

A colored-pencil sketch of a speculative hybrid warbler (cross between a Magnolia Warbler and a Northern Parula) standing in side view, mouth open as if singing. The top of its head, its wings and its tail are blueish gray, while its throat and belly are yellow that fades to white at the tail. A black mask covers the side of its head, and a black neck ring with black streaks marks its chest.

Such a wonderfully troll-shaped swamp monster, I’m super excited to see the upcoming documentary on this species in a few months! #kaimere #specevo

The ba'khar, a massive fish-specialized megaraptoran endemic to the Crescent of southern Ni'Khar, most abundant in the Seridic Wetlands. Males have a sail on their back for display and to anchor lifting muscles and ligaments of the neck. They also sport a pronged midline crest.

Adding a photo to this post: a weathered collection of osteoderms and bones from what was likely a juvenile Armadillo, probably left over from a pile of now-gone coyote poop. Something I found recently in the woods.

A photograph of a scattered pile of tiny, nearly rectangular, white osteoderms laying on the sandy ground amongst some pebbles and small leaves. Most are laying individually, though some are connected in groups of two or three or four. They are from a small armadillo, likely the last remnants of a piece of coyote poop.

Just barely making it for September’s #NearbyNature2025, here’s the Mexican Long-nosed Armadillo. Formerly known as a northern subspecies of the recently-split Nine-banded Armadillo, this is the only Xenarthran native to Alabama today. They are mostly nocturnal insectivores. #wildlife #alabama

I am so, so, so excited for this year’s Megaraptoran story!!!

A size chart of our megaraptoran mothers: a ba'khar and kurajaku.

Yodemi is a ba'khar in her late forties. A mother of over a hundred adults and many more young at the start of our story, including our protagonist, Fai Zhemi.

Mazhu is, conversely, a new mother, laying her first clutch.

Autumnal colors 🍂

As the days of the wet season become shorter in the fall & winter months of Ice Age California, the leaves of deciduous trees (Sycamore, Walnut, Willow, & Alder) will change color.

What appears to be the og post:

A screenshot of the earliest Facebook post I could find that shows the photo posted above, with a big black cat standing in a ditch.

Dynamognathus @dynamoterror.bsky.social · 13d

So, this photo has been making the rounds lately. There’s many posts claiming it’s from many places, but the earliest I can find puts it in Big Creek, Mississippi. It’s not AI, and almost certainly a Leopard, so someone’s either good at photoshop or lost a pet. Additional info appreciated. #wildlife

A picture of what appears to be a large, black felid standing in a densely vegetated, water-filled ditch just off a road, photographed through the open window of a truck. If it’s not a hoax, it might be a loose black leopard in Mississippi.

A mammoth cow and bull browse quietly together, their silhouettes mingling with a herd of bison as the light around them fades.

Scientific evidence suggests that mammoths used their massive tusks for social, defensive, and foraging behavior, much like modern day elephants!

Quick sketch of the face of Palaeoloxodon antiquus, a close cousin of living African Elephants that roamed across nearly all of Europe and parts of Asia during the Pleistocene. If not for human activity, it likely would have survived in much of its range to the modern day. #pleistocene #elephant

Black-and-white pencil drawing of the face of the extinct elephant Palaeoloxodon antiquus, with its large ears spread out and its wrinkled trunk hanging down between the splayed tusks.

A showcase of the oak savannas of Minnesota during the early Holocene, with emphasis on the herps. I drew this within four days to give to Ed and Emily of Snake Discovery, when they came down to the Atlanta reptile-expo in August. #holocene #paleoart #sciart #reptiles #amphibians #snakediscovery

A colored-pencil illustration of an oak savanna scene, taking place during the day in southeastern Minnesota during the early Holocene. A sandy well-worn path cuts across the piece from the foreground in the lower right corner to the background on the left side, curving around a bison-wallowing-pit dug into the sandy soil. Two large oak trees line the edge of the path, with many more scattered on the hill in the background. On that hill are two bison fighting and an elk observing them, while in the midground a mastodon skeleton lies scattered at the base of a tree. In the foreground, the details of small flowers and grasses are visible along with many snakes, a toad, a nesting turtle, a skink, and a bobcat.

A black-and-white version of the same Holocene-oak-savanna piece, but with a number in a small white circle next to each animal. Number one is the Elk/Wapiti just behind the hill, number two is a Timber Rattlesnake halfway in the bison-wallowing-pit, number three is the plains hognose on the edge of the same pit in the foreground, number four is an Eastern Meadowlark perched on the tip of a mastodon tusk, number five is a Bullsnake slithering through the same Mastodon skeleton and looking up at the meadowlark, number six is the American Mastodon skeleton itself, number seven is an American Toad very close in the foreground and staring straight at the viewer, number eight is a Western Fox Snake, number nine is the Bobcat approaching that fox snake, number ten is the pair of American Bison butting heads on top of the hill, number eleven is a Painted Turtle digging a nest at the base of the closest oak tree, and number twelve is a Prairie Skink climbing up the trunk of that same oak.
