Shortened version of whats below:

TL;DR: name of species: Machairodontinae its a saber tooth cat idk how to describe it but ye

Longer version:

The Machairodontinae contain many of the extinct predators commonly known as "saber-toothed cats", including the famed genus Smilodon, as well as other cats with only minor increases in the size and length of their maxillary canines. The name means "dagger-tooth", from Greek μάχαιρα (machaira), sword. Sometimes, other carnivorous mammals with elongated teeth are also called saber-toothed cats, although they do not belong to the felids. Besides the machairodonts, other saber-toothed predators also arose in the nimravids, barbourofelids, machaeroidines, hyaenodonts and even in two groups of metatherians (the thylacosmilid sparassodonts and the deltatheroideans).

The Machairodontinae originated in the early or middle Miocene of Africa.[citation needed] The early felid Pseudaelurus quadridentatus showed a trend towards elongated upper canines, and is believed to be at the base of the machairodontine evolution. The earliest known machairodont genus is the middle Miocene Miomachairodus from Africa and Turkey. Until the late Miocene, machairodontines co-existed at several places together with barbourofelids, archaic large carnivores that also bore long sabre-teeth. Traditionally, three different tribes of machairodontines were recognized, the Smilodontini with typical dirk-toothed forms, such as Megantereon and Smilodon, the Machairodontini or Homotherini with scimitar-toothed cats, such as Machairodus or Homotherium, and the Metailurini, containing genera such as Dinofelis and Metailurus. However, some have recently regrouped the Metailurini within the other felid subfamily, the Felinae, along with all modern cats. The last machairodontine genera, Smilodon and Homotherium, did not disappear until late in the Pleistocene, roughly 10,000 years ago in the Americas.Based on mitochondrial DNA sequences extracted from fossils, the lineages of Homotherium and Smilodon are estimated to have diverged about 18 Ma ago. The name 'saber-toothed tigers' is misleading. Machairodonts were not in the same subfamily as tigers, there is no evidence that they had tiger-like coat patterns, and this broad group of animals did not all live or hunt in the same manner as the modern tiger. DNA analysis published in 2005 confirmed and clarified cladistic analysis in showing that the Machairodontinae diverged early from the ancestors of modern cats and are not closely related to any living feline species. Saber-tooths also coexisted in many places with conical-toothed cats. In Africa and Eurasia, sabertooth cats competed with several pantherines and cheetahs until the early or middle Pleistocene. Homotherium survived in northern Europe even until the late Pleistocene. In the Americas, they coexisted with the cougar, American lion, American cheetah, and jaguar until the late Pleistocene. Saber-toothed and conical-toothed cats competed with each other for food resources, until the last of the former became extinct. All recent felids have more or less conical-shaped upper canines.

The jaws of machairodonts, especially more derived species with longer canines, such as Smilodon and Megantereon, are unusually weak. Digital reconstructions of the skulls of lions and of Smilodon show that the latter would have fared poorly with the stresses of holding onto struggling prey. The main issue was the stresses suffered by the mandible: a strong force threatened to break the jaw as pressure was placed on its weakest points.Smilodon would have had one-third the bite force of a lion, had it used only its jaw muscles. However, the neck muscles that connected to the back of the skull were stronger and depressed the head, forcing the skull down. When the jaw was hyper-extended, the jaw muscles could not contract, but the neck muscles pressed the head down, forcing the canines into whatever resisted them. When the mouth was closed far enough, the jaw muscles could raise the mandible by some margin.

On occasion, the bone of a fossilised predator is preserved well enough to retain recognizable proteins that belong to the species it consumed when alive. Stable isotope analysis of these proteins has shown that Smilodon preyed mainly on bison and horses, and occasionally ground sloths and mammoths, while Homotherium often preyed on young mammoths and other grazers such as pronghorn antelope and bighorn sheep when mammoths were not available. Examinations published in 2022 of tooth wear patterns on Smilodon and bite marks on the bones of the peccary Platygonus by Xenosmilus suggest that machairodonts were capable of efficiently stripping and de-fleshing a carcass of meat when feeding. They also show a degree of bone consumption on par with that of modern lions, which themselves can and regularly do eat smaller bones when consuming a meal

behind the carnassials. Regardless, reconstructions of Smilodon, Machairodus, and other species are shown with long lips, often resembling the jowls of large dogs.Studies of Homotherium and Smilodon published in 2022 by Mauricio Anton et al., suggest that scimitar-toothed machairodonts like Homotherium itself possessed upper lips and gum tissue that could effectively hide and protect their upper canines; a trait they shared in common with modern cat species, while Smilodon had canines that remained partially exposed and protruded past the lips and chin even while the mouth was closed due to their great length.

Comparisons of the hyoid bones of Smilodon and lions show that the former, and possibly other machairodonts, could potentially have roared like their modern relatives.

A 2009 study compared the ratios of social and solitary carnivores in reserves in South Africa and Tanzania with those of fossils of California's La Brea tar pits, a well-known fossil bed from the Pleistocene, and how they responded to recorded sounds of dying prey, to infer whether Smilodon was social or not. At one time, the La Brea tar pits consisted of deep tar in which animals became trapped. As they died, their calls attracted predators, which in turn also became caught. It is considered the best Pleistocene fossil bed in North America for the number of animals caught and preserved in the tar, and may be similar to the situation created in the study. The assumption was that solitary carnivores would not approach the sources of such sounds, because of the danger of confrontation with other predators. Social carnivores, such as lions, have few other predators to fear, and will readily attend these calls. The study concluded that this latter situation most closely fit the ratio of animals found at the La Brea tar pits, and therefore that Smilodon was most likely social.

These cats were tenacious and adaptable animals, thriving for hundreds of thousands of years before their time finally came to an end. Saber-toothed cats went extinct between 8,000 and 10,000 years ago, as the ice age drew to an end and their prey began to die out.

The name means "dagger-tooth", from Greek μάχαιρα (machaira), sword.

i love seeing ppl b like ugh i CAANT take how the fandom treats [character that im not necessarily consumed by but i enjoy from the sidelines and believe i have at least a loosely accurate understanding of them] but the post doesnt elaborate on what that terrible take is and since ive never even realized there was conflict over the type of person that this character is i get worried that i am the one making the characterization faux pas but upon looking into it i realize that actually no theres just a facet of fandom that i didnt even know about where people are saying the strangest shit imaginable

[thebestestdancers]

what happend to the photos

My paternal grandma Esther died at the end of July of this year. We had cleaned her apartment, and my dad had put all of the pictures and photos she had there in a huge box. He hadn't brought it to our home yet, because he was waiting for his sister to recover from an aneurysm surgery, so that we could sort all of the photos with each other.

He went there today to pick up the photos and he couldn't find the box. He went back with my brother, and they discovered some stuff.

My had given one of the doorsman the keys to her apartment. Then the doorsman gave the keys to one of the janitors. The janitor went into the apartment, saw the box with photos and believed we didn't want it anymore (even though no one in my family ever expressed that). He took the box and he left it at a trade fair. That was 15 days ago, and because my maternal grandma Lita died last week, no one had been there in that period of time.

My brother and my father's cousin went to the trade fair and they didn't find the photos, so they're lost.

We didn't have time to grieve grandma Esther, and now they took away our visual reminders of her. She had photos of me and my brother and our cousins when children, of my father when he was young, of my granpa, of her parents and her siblings. That box also had stuff like my grandpa's university graduation invite, something no one had found until I went there and that my dad was so happy to see. And now it's just all gone.

I'm fucking upset. I wanted to be a historian so photos and documents are important to me, and I was particularly excited to go through these photos ans now they're gone. Just the ideia of someone possibly treating them like trash or even ripping them, is breaking my heart. I heard my dad cry like never before, he never cried like this, not even when grandma actually died. He even said that for him, it was like she died all over again.

I'm just... I caant
