I like anything to do with the sciences, particularly the life sciences and the history of the Earth. Have a BSc in Zoology.

Selected species of Dimetrodon.
Here are various sketches showing some species of Dimetrodon, which was a quite diverse genus during the Early Permian. The genus includes about a dozen of species

A shake-up of the dinosaur family tree! Rhabdodontids are not ornithopods. They are ceratopsians.
There were horned dinosaurs in Europe! As shown by a new fossil of Ajkaceratops from Hungary!

Despite being ill I think this first formation #paleostream of the year turned out pretty good.
The Upper Elliot Formation from the early Jurassic of South Africa is an important piece for our understanding of sauropod evolution but beyond that it's just a really cool assemblage

It is now early Pliocene, Otodus megalodon have become a rare sight, let alone in great size. A vacuum in the marine ecosystem will be created in the wake of megalodon extinction. A void that Carcharodon carcharias, the great white sharks, ready to fill.

@realLPBeria Something crazy I learned recently is that some space probes apparently contained refined whale oil in some of their mechanisms (I think for their cameras, but I can’t quite recall).

This gruesomely gee-whiz description of commercial whaling from one of my dad’s childhood books conveys the sheer alienness of the ‘50s far better than anything on Mad Men:

@dennismhogan A fact I mention often is that the biomass of whales killed in the 20th century outweighs the calculated biomass of all living wild mammals.

@Riamus01 You can find a collection of his art here oceansofkansas.com/varner.html

Going down memory lane right now, so many youtube tribute videos and google searches back in the 2000s would show you pictures like these.
RIP Dan Varner...

Words cannot describe just how much I ADORE and feel nostalgia for Burian's Mosasaur paintings. I wish fantasy creature designs looked back at vintage paleoart because watching Burian's interpretations come to life with animation would be such a pretty sight.

@Riamus01 Have you watched “Scavengers Reign”? That show has a similar concept.

Of all the concepts of deities I've seen in fiction, Eywa has basically become my favorite.
It feels like the most realistic take on a God I've seen in fiction, because the more you think about it, it's basically a planet-wide mycorrhizal fungi that's essentially connected to

I feel like artificially-lit deep sea #paleoart is a unique artifact of our time where photography/video of the deepest parts of the ocean is fairly commonplace and accessible

Manipulonyx, a new alvarezsaur with really fascinating hands! The condition of the fingers isn't that unusual for the clade but the OSTEODERMS on the hand are new!

You know what, lets make this easier!
Below are all the formation pieces done this year, what were your favorites this year, which ones are you looking forward to!
Bugti Hills, Bahariya, Rio do Rasto, Gigantopithecus assemblage...

@TM9380 Do you know how the decay rate was originally calculated? Was is by using the decay rate of other isotopes with a known half life to verify, or can the rate be directly measured in a sample?

Because of that, uranium lead dating is generally used. These are aspects of chemistry and the like that are a bit beyond me so I’ll let the Wikipedia summary break it down…
English
A common question, one that’s often used as an attempt to disprove deep time and aspects of paleontology, is how do scientists date rocks and fossils. Assuming this is asked in good faith, there is an answer! It’s called radiometric dating, though there are different forms of it.

Continuing my exploration of Jurassic paleobotany, this time with ferns of the family Dipteridaceae. Fossil taxa like Clathropteris have a really interesting shape that for me is pretty difficult to get right.

Result from the Irdin Manha Formation #paleostream.
While you might never heard it's name you most likely have heard of some of the fauna from here. First and foremost Andrewsarchus.
The fossils were so far largely excavated by the amnh in northern China (Inner Mongolia) during

Someone shared this photo of a Black Bear crossing through a swamp in Southern Florida and it makes me want to see that with one of Florida's many fossil cats like,Smilodon, Xenosmilus Rhizosmilodon, or even Homotherium.
