So I am not the only one who is still bitter about the Norwegian calf?

Absolutely not. I was anti when baby Norway showed up and as far as I can recall only one other anti actually had the common sense and compassion to actually publicly want that calf rescued. It honestly was the most emotional, frustrating time I had ever had in the captivity debate, and it was absolutely the last straw I could take from the anticaptivity movement, so ultimately that was one of the several pushes I had towards becoming a procap.

For those who missed it, some highlights of Baby Norway’s short life include;

- Orca “experts” / “researchers” flat-out saying that they would not allow the whale to be rescued – “Indeed, put this orca in a tank/aquarium is not even an option!! Norway does not want to see “Morgan’s case” happening again!“

- Morgan, who entered into captivity an absolute skeleton and looked like a neonate at two years old, and is now a beautiful, vibrant, healthy adult female. They don’t want… that to happen again. Okay. Speaks volumes of the anticaptivity agenda, because what did happen with baby Norway, is that she stranded, barely alive after a prolonged period of starvation, and got a round of bullets in her head (exactly like another Norwegian calf that stranded a year before her).

- They completely ignored this fragile starving, injured, INFANT CALF. Oh, but they “talked about a plan” so that’s fine.

- The infant (Let me stress that. This was a neonate calf, days old at best.), visibly starving already when it was first seen, should have at the VERY least been secluded into a small pen and started on a nutritious formula. Instead, they tossed it fish. And I directly quote, “Its body needs milk of course, but at least some calories!”. The optimism is disgusting, considering what this calf was going through, on its own, without help.

- Baby Norway went missing for a while – it wasn’t known if she “found her family” like activists had been hoping, simply wandered off, or if she died. But she showed back up. This time she stranded and she was barely alive. She was given a lethal injection via her dorsal (the only warm place left on her body that had entirely gone cold) and then shot in the head with a shot gun, “just in case”. And that was it.

Baby Norway’s last moments.

Rest in peace, beautiful little girl.

Snowshoe hares’ traditional habitat in Wisconsin may not be white enough to provide the animals with cover as the climate changes.

“The snowshoe hare is perfectly modeled for life on snow,” said Jonathan Pauli, a professor of forest and wildlife ecology at the University of Wisconsin-Madison and a coauthor of a study recently published in Proceedings of the Royal Society B, in a release. “They’re adapted to glide on top of the snow and to blend in with the historical colors of the landscape.”

The snow is vital for snowshoe hares (Lepus americanus), who rely on it for camouflage from predators. But snow is becoming less common in the southern range of their habitat in Wisconsin…

Do animals have sex for fun? This video attempts to answer a question all of us might have asked ourselves at some point!

Updated visalization of every Vaquita left on Earth

There are supposed to be 5000 of them. Now there are 30.

What has been done so far has not worked, including the ban on gill nets, and the capture effort that is coming will probably be far too late.

This is humanity’s fault.

China for pushing the market for totoaba swim bladders, Mexico for allowing it until this point, and the rest of us for not stepping up until they are at death’s door.

This species will most likely be gone in one or two years, and it will be the second cetacean species to die out in a little over ten years, the second in the entire 200 000 year history of the human species.

It’s Jehol Biota Day!

The Jehol Biota is the ecosystem of the Yixian and Jiofotang Formations of northeastern China, dating between 133 and 120 million years ago in the Early Cretaceous (from the Valanginian to Aptian ages). 

It is famous because of it’s method of preservation - there were ash eruptions periodically, and the fossils are Lagerstätten, meaning that they were exceptionally well preserved with articulated skeletons, soft tissues, stomach contents, and even coloration. 

This has led to an amazing understanding of various types of dinosaurs and other prehistoric animals, especially very birdy dinosaurs. 

These animals lived in forests around lakes, dominated by conifers but featuring the earliest flowering plants - Archaefructus, which may have been a water plant.

There were dry seasons, but it was a mostly wet formation, as many of the plants grew in very wet habitats and probably stayed close to bodies of water. 

The Yixian Formation was the older of the two main Jehol Formations, and featured many, many animals. Of invertebrates, there were spiders, crustaceans, dragonflies, flies, wasps, many other insects, and molluscs, of too many to list. Fish included the lamprey Mesomyzon, ray finned fishes such as Lycoptera, Peipiaosteus, Protopsephurus, Sinamia, and Yanosteus, and a potential shark. There were frogs and toads like Callobatrachus, Liaobatrachus, and Mesophryne, as well as a salamander, Liaoxitriton.

There were mammals, too, of course - the stem-placental Acristatherium, the stem-marsupials Akidolestes, Maotherium, Zhangheotherium, and Sinodelphys, the stem-therian (Therians being the group of Marsupials and Placentals) Eomaia, the multituberculate (a group of mammals which seem to also be stem-therians) Sinobaatar, and a significant number of Eutriconodonts, a group of early derived mammals, including Chaoyangodens, Gobiconodon, Jeholodens, Juchilestes, Meemannodon, Repenomamus, and Yanoconodon.

There were the weird early derived Saurians (the group consisting of Lepidosauromorphs and Archosauromorphs, so Extant Reptiles), Choristoderans - Hyphalosaurus, which is known from thousands of specimens, and Monjurosuchus. Lizards included Dalinghosaurus, similar to the modern Chinese Crocodile Lizard; Liushusaurus and Yabeinosaurus, lizards relatedx to modern geckos and skinks, and Xianglong, a gliding lizard. Turtles included Manchurochelys and Ordosemys, both Cryptodirans, a group including giant tortoises, sea turtles, tortoises, snapping turtles, and others.

The heroes of the formation were, of course, the Avemetatarsalians. There were many pterosaurs - Beipiaopterus, Boreopterus, Cathayopterus, Elanodactylus, Eosipterus, Feilongus, Gegepterus, Gladocephaloideus, Haopterus, Moganopterus, Ningchengopterus, Pterofiltrus, and Zhenyuanopterus.

Ornithischians included the ornithopods Bolong, Jeholosaurus, and Jinzhousaurus, the ankylosaur Liaoningosaurus, and the ceratopsians Liaoceratops and Psittacosaurus. There were sauropods too - the titanosauriform Dongbeititan, a potential titanosaur, and an animal that has for now been referred to Euhelopus. But the real heavyweights were the theropods.

There were the tyrannosauroids Yutyrannus - one of the best known tyrannosauroids with feathers - and Dilong; the compsognathus Huaxiagnathus, Sinocalliopteryx, and Sinosauropteryx - the first non-avian dinosaur known to have feathers, and also with known coloration; early Ornithomimosaurs such as Hexing and Shenzhousaurus; the early derived maniraptoran Yixianosaurus; Beipiaosaurus, a therizinosaur; and tons of Chickenparrots, such as Similicaudipteryx, Protarchaeopteryx, Ningyuansaurus, Incisivosaurus, and Caudipteryx.

There were many Dromaeosaurids (raptors), such as Graciliraptor, Tianyuraptor, Zhenyuanlong - a raptor known from nearly complete feather traces, including extremely large wings - and Sinornithosaurus, the first Dromaeosaurid found with feathers. There were also lots of Troodontids, such as Sinusonasus, Sinovenator, and Mei, as well as unnamed members of both groups. There were early-derived Avialans such as Zhongornis, Jixiangornis, Confuciusornis, and Changchengornis. There were loads of Enantiornithines, such as Bohaiornis, Eoenantironis, Dalingheornis, Liaoningornis, Longirostravis, and Shanweiniao - an Enantiornithine that had a tail fan like modern birds. There were also Euornithines - the group which contains modern birds - such as Longicrusavis, Hongshanornis, and Archaeorhynchus. In short, this was an extremely birdy formation indeed.

The Jiuofotang Formation was slightly younger, but was similar to the Yixian in terms of the animals there. There were ray finned fishes such as Jinanichthys, Lycoptera, Peipiaosteus, Protsephurus, and Sinamia. There was the mammal Liaoconodon, a Eutriconodont, as well as an unnamed mammal similar to Eomaia from the Yixian Formation. There were also Choristoderans like Philydrosaurus, Ikechosaurus, and Liaoxisaurus.

There were many, many, many pterosaurs. This included Chaoyangopterus, Eoazhdarcho, Guidraco, Ikrandraco, Jidapterus, Liaoningopterus, Liaoxipterus, Linlongopterus, Nemicolopterus, Nurhachius, Shenzhoupterus, and Sinopterus. And, as we shall see, there were a lot of flying theropods as well, indicating that the two groups did live alongside one another just fine, and the common narrative of “birds replaced pterosaurs” has little foundation in the fossil record.

There were only a few Ornithischians - namely Chuanqilong, an ankylosaur, and Psittacosaurus, a ceratopsian. There is also an unnamed titanosaur from the formation. As for theropods, there were a lot. The tyrannosauroid Sinotyrannus was the largest predator there, there was the Chickenparrot Similicaudipteryx, and of course one of the most famous raptors, Microraptor, which was a four-winged Dromaeosaurid that we know had iridescent black feathers.

There were many early derived Avialans, such as Confuciusornis, Dalianraptor, Omnivoropteryx, Sapeornis, Shenshiornis, Zhongjianornis, and my personal favorite, Jeholornis, a theropod we know was a seed-eater, which is actually quite hard to determine from fossils. There were many Enantiornithines, such as Alethoalaornis, Boluochia, Cathayornis, Cuspirostrisornis, Dapingfangornis, Eocathayornis, Gracilornis, Huoshanornis, Largirostrornis, Longchengornis, Longipteryx, Rapaxavis, Xiangornis, and one of my favorites, Sinornis, which is thought to have perched. As for Euornithines, there was Chaoyangia, Jianchangornis, Parahongshanornis, Schizooura, Songlingornis, Yanornis, and Yixianornis.

It’s plain to see why the Jehol Biota is so fascinating. At least for me, I love it because it’s clearly one of the best pictures we have of Pennaraptoran evolution - the amount of birdie dinosaurs is absolutely ridiculous. But there’s really something for everyone here - there are titanosaur-like things, some of the earliest Ceratopsians, tons of Pterosaurs, weird Choristoderans, and even some insights into the evolution of early mammals and different types of amphibians and fish, as well as the first flowering plants. The Jehol Biota is one of the best ecosystems we know about, and it definitely deserves celebration!
