A ‘raptor’ is a creature that resembles a dinosaurian raptor, but unlike their namesake, these creatures descended from a hexapedal ancestor, meaning that they are six-limbed.

Raptors are most similar to avians in nature, but their short wingspan renders them unable to achieve true flight. Instead, their wings are used primarily as cover, as their normally smooth hide is capable of changing color and texture to blend into their background. 

While they prefer to use ambush tactics, raptors are fully capable of planning and executing sophisticated hunting strategies together with the rest of their tight-knit pack, which is led by dominant matriarch.

The Raptor: an spec-evo species made by @second-sol that i got commissioned! It was really fun to play with the pattern and test my skills at making raptor-like creatures.

Wingei's short-faced-bear.
A commission for @pedrohenriquetunes 

Made in late 2024, this commission was my take on one of the many species of bear across South-America, which people commonly assume that no bear could even live there or there isn't no actual bear species around.

Then i present to you the Andean Bear, the last remaining Short Faced Bear (Tremarctine) species on the Americas: but back then there was many more bears with different ranges, sizes and diets across South America.

This reconstruction was conducted by Pedro, but with a bit of my touch and style on the animal. A more light colored coat with black reminiscents making homage to some Andean Bear specimens with more lightly colored areas(Pedro's suggestion): trying to imagine a bear that lived from the Caatinga biome(a savannah-like biome, therefore being in contact with some degree of heat) of Brazil(being the predominant species of Bear around here), the Argentinian Patagonia and Mexico. Arctotherium wingei had a predominantly omnivorous diet, ranging from scavenging carcasses to eating vegetables. 

Pedro has a passion for bears, and his current work and studies circle around these beautiful creatures. This piece won't be the last about bears, with more coming along regarding these animals.

Diplomachairodus triantafillos (The Rose Double-Fanged-Cat)

Diplo-machairodontinae (dual knife in greek) or Diplomachairodus is a big cat tribe known for having the unusual two-pair of elongated canine teeth on both sides of their upper mandibles, a much more extreme adaptation compared to those of more commonly known Saber-Tooth cats such as Smilodontini and Homotherini tribes.

Differently from their close relatives, this family has only one extant member alive and he's the only cat within this lineage as we know it.

Also called as Amur-Double-Fanged-Cat, Giant-Rose-Tiger, Imperial-Leopard or King-Leopard: this cat is one of the largest cat species alive today, if not the largest: being perfectly adapted to Taiga-like forests and mountainous regions.

Yesterday i was caught by surprise by a study that showcased to the world the first glance of a Saber Cat with flesh and blood. Homotherium latidens is once again described on the Late Pleistocene, in the form of a cub. This reconstruction takes into consideration the pigmentation loss and eventual differences on adult and younger individuals, applying a lighter pelt than the one described by the study.

This was made by comparing cubs and adult individuals from modern cats, then stabilizing which features are more common and those who are not. Afterwards, i used my color palette and color identifications to measure the differences in tones by %.

Eventually, i had to deal with the permafrost mummified state which certainly degrades the original colors. So, from the cave lion cubs previously described, i tried a way to restore.

And finally, i used the "restored" calculated colors to produce adult colors following the patterns and measures in the first step.

I'm still speechless, i can't believe i had the chance to see a Saber-tooth, an animal long gone, now feeling so alive and near: despite still being extinct.

I wish that i can atleast see one walk and grow one day.

Ladies and Gentlemen, Homotherium latidens. The Scimitar-tooth Cat, remade and reconstructed based on the unique saber-tooth cub of Yakutia.

In Spring, it's morning and a mother short-faced bear walks by a field in bloom while her cub stands up and looks off-screen curiously. There are two trees with lush green leaves to the left, and hazy mountains in the background. A flock of ducks or geese flies in formation in the sky.

In Summer, it's noon and a herd of wild horses grazes in the field. The trees are green, the mountains are lush with greenery, and the sky is blue.

In autumn, the sun is starting to set and a lone Homotherium lets out a call, with visible condensation coming out of his mouth. The field is drab, the trees have yellow leaves and the mountains in the background show a brown landscape.

In winter, the sky is overcast and it is snowing. A herd of mammoths crosses the snow-covered field, while a white hare moves out of the way. The trees are leafless and the mountains are also covered in snow.

I really enjoy doing series with fixed landscapes showing the passage of time and native fauna. I previously shared one I've made with different times of the day in Pleistocene Central Brazil, and here is an earlier one I did showing the four seasons in Ice Age Beringia (America-Asia land bridge).
