Happy #FossilFriday, check out the skull of Eryops! This inarguably adorable face was filled sharp teeth, perfect for holding onto slippery, wet prey. Often erroneously called an amphibian, this animal is instead a member of an order known as temnospondyls. (1/2)

Happy #FossilFriday, check out the skull of Protoreodon! While the top of the skull is somewhat crushed, the teeth are overall well-preserved; take a look those cute little canines! This little animal is an ancient and distant relative to modern artiodactyls, such as deer and cattle.

They might have tried to nibble on you a bit, but these were made by pretty small animals, probably no more than a couple feet tall at the shoulder! Worst they could do is nip you pretty good!

Happy #FossilFriday, check put some darling crocodylomorph tracks! 200 million years ago, small and snappy distant-croc-relatives, like Protosuchus, darted and splashed along a ripple-marked lakeshore and through silty riverbeds, leaving behind their traces. (1/2)

Thank you! I agree, there's something just delightful about more organic ships. They just feel like they'd fly better!
And, yeah, a regular sailing ship can feel out of place! Granted, it IS really funny to just fight a galleon full of pirates in space, but I do think that spaceships should be more than, well, ships!

Ooh, very cool! I can definitely see some one-person spelljammers--kind of like merrenoloths and their vessels. It would be very unnerving to go up against a powerful lich in a souped-up ship!
In the current campaign I'm playing in, the spelljammers are manned similar to sailing ships, though the spelljammer's pilot tends to act as both helmsman, navigator, and sometimes captain. My character is the current pilot, though she avoids acting as a captain as much as she can!

Happy #FossilFriday, take a look at the skull of Teratophoneus! This tyrannosaur made southern Utah its stomping grounds roughly 76 million years ago, and it may have used those massive teeth to prey upon hadrosaurs such as Gryposaurus and Parasaurolophus. (1/2)

She looks pretty cool here, but what I DIDN'T show is her losing half of her HP about two seconds after this after a scavver scored a crit on her. She likes to only remember the part where she wasn't full of shark teeth.

This is a scene from a recent DnD session in the Spelljammer universe! Normally, Crumbs prefers to stick to jamming/piloting, but when two of her crew members kept failing their check to reel in another crew member that went overboard, she decided to step in with some cover fire.

2025-02-18 14:16:06 UTC

Unwilling to have bite-sized chunks taken out of her ship, Crumbs heads up to the top deck blast some marauding scavvers.

Not only are they gorgeous on the outside, some specimens can have particularly beautiful interiors, like this crinoid stalk with a flower-shaped body cavity. This stalk once held a crinoid to the ocean floor, securing it against the currents as it filtered the water for nutrients. (2/3)

While superficially similar to crocodiles, phytosaurs have a few key differences; one of the main ones is that their nostrils are located close to their eyes. Some species have particularly large nasal crests, and individual variation in crest size has been suggested to be sexual dimorphism. (2/3)

Haha, the names ARE super fun! :^) My partner, who is running our campaign, came up with them!

Showing off this spacesuit sheet I made for our current Spelljammer campaign! Since we have modular spacesuits with all sorts of components to keep track of, I wanted to consolidate all the info into one place.

Oh, I'll still be posting here! :^) I just literally cannot check my notifications without the app crashing, so I've already missed some replies/mentions from people on here. I just want folks to know they have another place to reach me if necessary!

This is a good time to remind ya'll that my notifications are pretty busted here, and that I'm way more active on Bluesky! If you want to make sure I see that thing you tag me in, or if you want to see more of the things I like, this place is your best bet!

Ooh, I haven't, but my partner and I have enough extra pieces that we could probably figure something out! I'll bet there's a few guides online too

I figured ya'll might like to see the Dungeons and Dragons wall in my home :^)

Not only have I been having to deal with getting tagged in an insane number of spam posts, now this app keeps crashing every time I try to check my notifications so I can report one. 😭 Anyone else having similar issues?

A young Juniper investigates her grove's newest visitor, unaware that a hag has placed a target on her head--or rather, her horn.

For a size comparison, here's me next to a replica of a Brachiosaurus shoulder bone, otherwise known as a scapulocoracoid. These bones help form the pectoral girdle in dinosaurs, and in sauropods, they also provided a sturdy attachment point for their pillar-like forelegs. (2/3)

Happy #FossilFriday, check out these hip (right) and shoulder (left) bones from Supersaurus! These huge sauropods wandered wide playas and fringes of thin forests during the Late Jurassic, and they were among the longest of their kind, possibly reaching up to 130 feet in length. (1/3)

Some zookeepers find Triceratops difficult to handle well before they're fully grown.

For sure, those are osteoderms, or boney armor plates! They're smilar to the osteoderms on ankylosaurs, like Ankylosaurus, but Ceratosaurus had just a line of them running down its back (and possibly other ones elsewhere on its body, it's difficult to say). They may have provided additional protection during scuffles with other predators, and/or they may have been used for display. Below is a picture of some Ceratosaurus osteoderms housed at the Natural History Museum of Utah.
