Homotherium ischyrus on the basis of a nearly complete skeleton from Birch Creek, Idaho. in general morphology the animal is similar to the Old World species Homotherium latidens, but some characters such as the retention of a two toothed third upper premolar in the mandible and an elongated lumbar section in the vertebral column suggest an early separation from the Europe lineage.

Most of the photos shared by the posters on Wildfact are copyright of someone else. 

By sharing the source, not only are you giving owners their due credit, you are also making additional details available to the viewers of your post & may hit other interesting material related to it.
It is also a great way to double check the authenticity of images & find better quality versions of them.

To encourage the habit sharing of links & credits to photographs' source website/profile/article, here's a reliable & easy to use "Reverse Image Search" engine:
Prepostseo Image Search

What it is & how it works.

Upload the image normally like you'd do otherwise. For example:


Simply copy the images url (in edit mode, or by opening it in new tab).

Open the Image Search & paste the link, or directly use the upload image feature. Press "Search Inage".


It will show available search options with multiple major search engines.


Unless the original image is in some private profile or gallery, there is a good chance that you'll find other copies of the image on the internet.


In this case, a WWF article:


Often people surf through Internet once in a while & hoard all good stuff they find. Later on while posting those one might have no idea where he/she had found them, or who the photographer was.
Even if someone bookmarks every one of them & individual photo sources are still hectic to find from the pile.

Give it a try.

This species displays the classic features of the genus, with skull similar in size to that of the jaguar, moderately flattened canines, large carnassial and a rather primitive mastoid region. The first fossils of this species known to science were a damaged skull and an upper canine found at the South African site of Sterkfontein, as described by R. Broom in 1937.

I'm very surprised that this forum doesn't have a thread dedicated to 'Shark predations'... considering the fact that Sharks, especially the Great White, is one of the greatest and easily the most fearsome and devastating predator on earth! So, i'll start one...

"Sharks are apex predators throughout the ocean, yet relatively few studies have quantified or determined factors influencing their hunting behaviour and predatory success rates. The waters surrounding Seal Island in False Bay, South Africa, provide a unique opportunity to study predator-prey interactions involving Great White Sharks (hereafter white sharks). During the winter, white sharks visit Seal Island to hunt Cape fur seals. About 48% of surface attacks on seals result in successful kills. Attack frequency is high, averaging 6.68 per day, with as many as 43 recorded in a single day. Sharks attack seals on the surface via a sudden vertical rush, which propels predator and prey out of the water in an awesome display of power and acrobatic prowess"...

I have seen many of posters including our great mod team, sometime posts various type of data related to animals. These data includes but not limited to Weight, body measurement, fossils measurement, evolution of species, statistics, counting, availability, progress and many other things.

For broader reach, effectiveness and easy to understand use Infographics to represent these data. Read about What is infographics - https://en.wikipedia.org/wiki/Infographic
You can use photoshop, Adobe Illustrator or free online tool like canva.com to create these images.

Posting the data in plain text is not best practice and does not reach broader audience.

The test is over. Googled the answers. My score is falling short of projected cut-off, not by much, but enough to bury the chances of me getting lucky.
Done my analysis. Identified my shortcomings. Drawn up plans for next attempt & aiming to meet UPSC-2019 better prepared. Another year of grinding...

But before that something i've been looking forward to, India's oldest zoo. The Alipore Zoological Garden is being renovated & new enclosures built.  
Some of the enclosures are more then 100 years old. I hadn't been there in years & i just had to see the place one last time before the older structures are demolished. 

The highest recoded attendance till date was on January 1, 2018 with 110,000 visitors. Thus i had to make sure i avoid the mob, or the animals don't come out of their shelters (standard practice here is for about 1/4 of the enclosure to be private space). So, i went on a weekday with the monsoon pouring down cats & dogs. The enclosures sure looked beautiful & lush but it meant some prized new arrivals like the Mouse deers were barely visible.

Chowsingha, the Indian four horned antelope.


Barking Deer.


Swamp Deer.


Nilgai or blue-bull female. The male was somewhere behind the bushes.


Cheetal or spotted deer, much larger up close than they look in photos. This facility is also used as a breeding centre for them. If i remember correctly, these animals have cousins that have been released in Sundarbans.


In the reptile house; Russell's Viper.


Burmese Python. (The sign says "No photography" so i decided to stop)


My favourite & Bengals state animal, Fishing cats. 




Jungle cat.


The new leopard enclosure. He's on that tree. Eyes could see him but camera couldn't.


Old Aviary. Hexagonal structure with 6 triangular cages. Peacock & Saras crane in the back.  


The one in last image.


Peafowl's housing.


New aviary.






At this point the rain got harder. I stood under the shed infront of the leopard enclosure. He came out & started pacing in the downpour.


Rhino (female). She has a calf who was behind the privacy wall. Her horn had been shaven for safety.




Tigress Rani didn't come out of her cavern.


New enclosure for tigers, presently houses a mating pair of a regular coloured female & this male (that's him in post #1,600 in Tiger Extinction thread back in his old cage). 






Most of the old cages are gone. Only 3-4 remain, with two animals still living there. This female...


...& this ex-maneater from Sundarban (In third video of post #1,600). Unlike previous times i was taking a note of their physique this once. 
He is exactly the similar to the mainland tigress in both size & stature, bigger head though. Shouldn't weigh very different.


It wasn't a day to be sitting in the water. It was damp & raining with quite a nip in the air. Helps him relive memories, i guess...

Well, the whole world is enjoying the Football world cup and everyone has picked their favorite team, even those whose country is not playing in this tournament.
Whom you are supporting ? Are you excited ?
So generally this thread is for all of us who love football and want to have friendly conversation

A complete run down in all things chimpanzee in terms of predation
