A stratigraphic column figure showing the formations of the Potomac Group, aligned to the Geologic Time Scale (Aptian-Cenomanian) and local pollen zones. The colors for each formation block grade from reddish brown at the bottom (Patuxent Formation) to olive at the top (Raritan Formation)

Use creativity in designing your stratigraphic figures! For this one (in McDavid and Thomas 2025), I sampled color values from pictures of rocks from the Patuxent, Arundel, and Patapsco Formations, and then extrapolated the trend forward for the Raritan.

It's always contradict that as a ichthyologic student always wants to find the target species in the fish market, another hand you want them to keep away the fishermen's net.

Testing the movement for the Shark Cranial Kinesis model. Think this is pretty close?

Shark/marine/anatomy people, I'd love your feedback! Intended for outreach for "general public". In the final version the parts will each be a different color.

St. George, famed slayer of endangered reptiles, squares up to an enormous, dark Tyrannosaurus in the dead of night. His white horse rears in panic at the looming giant, who casts a great shadow over them both. George aims his lance up, conscious that his weapon is a mere needle to his 10-tonne opponent. "I much preferred being painted by Paolo Uccello", he thought to himself. "He made the reptiles small, gangly, and fictional. I didn't sign up to fight real giant reptiles, and I _especially_ didn't sign up for being painted by someone who clearly wants the reptiles to win." Moments later, George's feeble lance broke upon the scaly, rib-lined belly of the tyrannosaur. He had a split second to respond: now defenceless, flight was his only choice! But before he could even begin to steer his horse away, he was wrenched from his mount and tossed back into the dinosaur's jaws. His final sensation was being crushed by spike-like teeth, his flesh mangled and cut by his own dark armour. The chewy flesh and metal confused the king tyrant, but she swallowed him whole anyway. The experience reminded her of eating an ankylosaur, but this had a greater taste of... justice? As if centuries of reptilian persecution by humans had been avenged, in a minor way at least. She walked off into the night, not bothering to chase the horse, who galloped into the nearby treeline. Her legend, Tyrannosaurus the St. George Killer, had begun.

I missed #StGeorgesDay, but what the heck: here's St George vs. #Tyrannosaurus for #FossilFriday. You don't have to look hard for the Paolo Uccello reference, but this Tyrannosaurus looks to be giving St. George a tougher time than the dragon in his painting. #paleoart #sciart #dinosaur

Introducing the BDJ portal, hosted on the @gbif.org platform!

Another initiative that will make it easier to use and reuse biodiversity data.

More @pensoft.net journals will soon follow suit!

A spectacle to behold, in the shallows, hugging this island, we see broad cowtail rays and mangrove whiprays - and looking with a close eye, few juvenile blacktip reef sharks weave between the rays.

What a wonderful day! Even though it's freezing outside, I still made a big progress.

Oh sure, when I eat a crinoid and vomit, nobody cares . But when a fish did it 66 million years ago & we just now find its puke, that's somehow big news.

(P.S. This find is also a great example of ichthyological ichnology, or ichnological ichthyology. 🧪🐟)
