Spangled coquette - Wikipedia

Today, according to my 12yo, is Spangled Coquette Awareness Day!

The males of this South American hummingbird have a spectacular crest.

This article says β€œsedentary” which confused me for a hummingbird but I read further to realize that simply means it’s not migratory… not a couch potato.

An excellent three-post take on one of the many facets of the recent Spinosaurus/Myhrvold/Epstein controversy. Science journalists, this story really needs covering! #scicomm #science #ethics #epstein

I've never paid much attention to the European wild boar included in the artiodactyl display but today it occurred to me that its pose _might_ be based on that of the famous Italian statue shown here, first written about in the 1550s, stolen and taken to Oxford, and cast many times in bronze...

I've written at length about the Blue whale model, the very first of its kind and built to accompany the Irish skeleton from 1891 now known as Hope. So I'll avoid talking about it again... there's tons to say. It was constructed by Percy and Stuart Stammwitz in 1937 and 38...

Everyone loves Lagenorhynchus... err, I mean Cephalorhynchus cruciger, the brilliant Hourglass dolphin of the far south. I've always enjoyed looking at the NHM model of it, but today I noticed... you can see its teeth!! I never noticed this before.

Today I noticed - I think for the first time - that some of the scars on the Risso's dolphin (a species I've seen in life, once at close range) are very specifically meant to be squid arm scars... brilliant detail!

Aplomado Falcon, Brazil

In my mind, the Aplomado Falcon is the prettiest falcon out there. I was fortunate to see my first ones in Brazil nearly a decade ago, and have photographed them a few times since.

Like everyone else, I was pleasantly surprised by the news of spinosaurus mirabilis being officially named and described. And reading how we have material from multiple distinct specimens is amazing. I was not gonna slouch on the flood of new paleoart depicting it.

Myhrvold has denied a friendly relationship and any wrongdoing. But it's pretty tone-deaf that coverage of this paper isn't addressing his involvement, especially when he's prominent in the authorship (3rd of 28). Lots of questions need answering about this, and our media have failed to ask them.

Records show deeper ties between Epstein, ex-Microsoft exec Emails show a yearslong relationship from at least 2010 through 2018, according to documents released to the public last week.

I mean, yes, fun dinosaur stuff is fun dinosaur stuff. But Myhrvold is mentioned in the recent batch of Epstein files over 1000 times (far more than Horner). Some of the correspondence between the two is very chummy and concerning. See: www.seattletimes.com/business/loc....

New fossils may settle debate over mysterious sail-backed spinosaurs Spinosaurs have sometimes been portrayed as swimmers or divers, but a new species of these dinosaurs bolsters the idea that they were more like gigantic herons

In which I provide a few thoughts on the new Spinosaurus species, S. mirabilis.

www.newscientist.com/article/2516...

I also stressed the deep connections between one of the study authors - Nathan Myhrvold - and Geoffrey Epstein to New Scientist. They didn't mention it, neither has anyone else.

Love this, the sand tiger looks very like a smalltooth sandtiger, which I think is one of the most underrated sharks and a great basis for a sort of generalised lamniform look

TakahΔ“ were thought to be extinct until 1948.

When I first learned about them as a kid visiting New Zealand in 1981, there were only 100 birds and I desperately wanted to see one.

Now there are 500 birds. Yesterday I first saw themβ€”seven in one day. Thank you, NZ, for brilliant conversation work.

Finished the final piece for the shark book - the electric ray Eotorpedo zapping a sand tiger in the Early Eocene. That concludes 80 pieces generated for the book. Got me a sore right hand that smacks of RSI so going to relax then get back to doing some commissions and a bit of art just for fun.

Today's feel-good story: a tegu rescued from the snow by a kind person in Providence, RI, has been saved by ET Reptiles & New England Wildlife Center. Usually, pet reptiles die in these circumstances, but frostbite treatment worked. @rickclaypool.bsky.social even visited the tegu + took this photo.
