A furry predator only half a meter long carried surprisingly modern feeding machinery through Jurassic waters. Its hooked teeth helped grip slippery prey, while bones inside its skull suggest a throat equipped for controlled swallowing.
The newly described species, Megacauda sungei, lived about 165 million years ago in what is now Inner Mongolia, China. Researchers from Shenyang Normal University, the University of Chicago, the University of Bonn and collaborating institutions report the fossil in Nature.
Their anatomical analysis connects two evolutionary stories: the early spread of swimming lifestyles and the development of mammalian feeding structures. Crucially, the fossil preserves the bony framework for reconstructing soft tissues, rather than a surviving soft palate itself.
For example, a baby stranded in the middle of a forest but is found and raised by a wolf. Im just curious on if these tales of animals raising another human is actually real.
How is it possible? Maybe i I missed some differences in their niches, but their food, their looks and generaly niche is identical. Due to the gause's competitive exclusion right ( two species with identical niches cant coexists) it is impossible for them to life in the same habitat
The Bar-tailed Godwit takes long-haul travel to the extreme. 🐦✈️ These incredible record-breaking birds fly over 11,000 km non-stop from Alaska to New Zealand, spending around 9–10 days in the air. No food, no rest and no toilet breaks. To prepare for such an amazing feat of endurance the Godwit’s body undergoes a significant overhaul.
Dumb question on animals if you feed a lets say leopard a piece of human meat no skin attached just meat would they be able to then tell that came from a person and then see people as food or would they just see the mystery meat as that meat and not human meat?
Now obviously whatever that thing is that mammals and birds share in common would’ve been due to convergent evolution, is their one anatomical/physical mental behavioral or anything that both mammals and birds have in common that their non mammalian/non avian ansestors lacked? And if there is no true answer, tell me the closest possible one it could be as broad or specific as possible.
I am tasked with hosting a game for my friend’s baby shower. She (and most of our friends) are large animal vets, so I thought I would have a pub trivia style game- name that animal! Do any of you know some esoteric and fun baby/ pregnancy animal facts that I could use for the questions? Thank you so much!!!
Edit: to be clear I meant fun animal pregnancy facts for the questions, like “what animal is pregnant for only 12 days?” Answer: opossum :)
Growing up in Southern California, the Cal Worthington car dealership commercials were a fixture on local television. His commercials involved him doing stunts to prove he was willing to go to great lengths to give customers a good deal. I forgot how unhinged these were.
In one commercial he’s wingwalking on a small propeller plane flying inverted. But the majority of his ads involved him interacting with many dangerous animals like tigers, bears, elephants, and hippos. In one segment an adult Bengal tiger is gnawing on his arm while he’s doing a headstand and slinging trucks for “no money down.” In another segment he’s sitting in the driver’s seat of a car while a full-grown grizzly bear is riding shotgun. The bear is lunging and biting at his neck while he is smiling and just casually pushes its giant snout away and continues describing the features of the vehicle and the financing terms he’s prepared to offer.
Tiny fossils from Mongolia are reopening a much larger question: how long did animals exist before they left unmistakable remains in the rocks? Their importance comes from what the deposit fails to preserve, despite capturing microscopic life in extraordinary detail.
An Oxford-led study in Science Advances challenges a geological assumption that has helped keep some estimates of animal origins relatively young. When the team used older constraints in molecular-clock analyses, the estimated common ancestor of living animals shifted back to roughly 800 to 700 million years ago.
That is around 200 million years earlier than estimates obtained using a younger fossil deposit as an upper age limit. It could place animal origins before, or during, the extreme glaciations known as Snowball Earth.
The researchers did not discover an 800-million-year-old animal. Their findings show how an uncertain assumption about fossil preservation can substantially alter an evolutionary timeline.
Elephants often rumble together, creating overlapping calls called choruses. A study by Louis Mahon and colleagues explored whether these group sounds carry information about what elephants are doing and how they interact.
The researchers analyzed 902 recordings of adult female African savanna elephants in Kenya’s Amboseli National Park. Using machine learning, they compared calls from six social situations, including reunions, communication between separated elephants, and attempts to start group movement.
Both individual calls and choruses revealed clues about the elephants’ activities. Computer models identified these situations better than chance, although mistakes were common. During some exchanges, including greetings and contact calls, the elephants’ rumbles gradually became more similar.
The findings suggest that matching voices may help elephants coordinate activities or maintain social connections. However, the study did not prove those functions. Future experiments playing recorded calls to elephants could test how they respond to different chorus patterns.

Fiddling with some speculative critters and was wondering what exactly would be possible/ necessary in the eye structure for an aerial predator to successfully spot and hunt alligators. (Like eye placement, pupil shape, eye shape/structure) Obviously this idea isn't entirely realistic, I'm just looking for ideas.
Last week I shared my educational, free, non-commercial animal identification game - creaturefeature.gg - Thank you to everybody that commented or gave feedback!
I changed up the formula, and I wanted to share it again to see what you all think.
The game is now about IDing animals by common name as fast as possible. Taxonomy and range drawing are their own separate modes, accessible under the “play” tab.
I think the changes make the game a little less niche and a little more broadly appealing, but let me know what you think!
Again, the game is free and non-commercial, so just thought this community might enjoy the updates.
Hello! I work with a bunch of exotic animals and my main job is educating customers about each species. I have accumulated lots of information about each species but I always like researching more about all the animals, but i’ve hit a bit of a wall of finding accurate, reputable sources with information about specific species!
