“In the course of twenty million years, mammals got more and more successful until they were the biggest, fiercest, and most spectacular animals on the planet. Whatever the climate, whatever the habitat, mammals made it their own. Their great strength was their ability to adapt. They grew to gigantic sizes, they evolved into powerful killers like the famous sabre-tooth cats, and they even laid claim to the oceans.”

- Kenneth Branagh, prologue to “Walking with Beasts”

Antrostomus vociferous, better known as the eastern whip-poor-will or whip o whill, is a species of bird within the nightjar family, Caprimulgidae, which is endemic to the deciduous forests and mixed woodlands of North and Central America from Canada in the north to Costa Rica in the south and from the east coast to the great plains. Often migrating to the north of there range to breed and to the south of there range to overwinter. It is named onomatopoeically after its song as whilst the whip-poor-will is commonly heard within its range, it is rarely seen because of its elaborate camouflage. Eastern whip-poor-whills are a nocturnal species which spends there days resting amongst leaf litter, tree roots, branches, hollows, and fallen logs, emerging at night to feed upon various flying insects such as beetles, flies, mosquitos, and in particular moths. Eastern whip-poor-wills are generally solitary preferring to spend time on their own; however, during migration, they may form loose flocks. Reaching around 8.5 to 10.5 inches (22 to 27cms) in length, 1.5 to 3 ounces (42 to 85grams) in weight with a 17.5 to 19.5 inch (45 to 50cms) wingspan, eastern whip poor whills sport a large head and broad body. They have mottled camoflauged plumage: the upperparts are grey, black and brown; the lower parts are grey and black. They have a very short bill and a black throat. Males have a white patch below the throat and white tips on the outer tail feathers; in the female, these parts are light brown. Breeding often begins in March, with pairs meeting up and building a loose nest on the ground, in shaded locations among dead leaves. Here a female will usually lay 2 eggs at a time. Incubation lasts 19-21 days performed by both parents. Eastern Whip-poor-wills lay their eggs in phase with the lunar cycle, so that they hatch on average 10 days before a full moon. As when the moon is near full, the adults can better forage at night and capture large quantities of insects to feed to their young.The chicks hatch well developed covered in down but with their eyes closed. They are fed and protected by both parents and start to fly at the age of 20 days. Eastern whip-poor-wills usually produce 1 or 2 broods per year and females may lay a second clutch while the male is still caring for chicks from the first brood. Under ideal conditions an eastern whip poor will can live up to 15 years.

little snapshots of a mod i have been working on for a few days, cenozoicraft, understandably based around adding cenozoic animals to the minecraft world along with neolithic tools. its heavily based around hunting and utilizing animal parts. most of what is here is tamable and rideable with fun little taming mechanics, so dont expect to be able to waltz up to a smilodon. more to come soon

Super happy with how plush and Friend-Shaped he turned out. Definitely need to draw some more Cenozoic creatures…

It's frickin bats !!

Onychonycteris ("Clawed bat") is the earliest bat known to science. It lived in the area of what is now Wyoming, USA during the early Eocene epoch (about 52.5 Mya).

Bats are small placental mammals that live all around the world. They're known for their creepy wings, nocturnal lifestyle, and cave-dwelling habits, as well as many other things. They are the second largest order of mammals after rodents, with over 1,400 species. They belong to the superorder Laurasiatheria, which also includes cats, dogs, bears, horses, whales, and a lot more, but that's about as specific as we can get with our current knowledge.

The origins of bats are mostly up to speculation. We estimate that they probably first appeared around 65 Mya, just after the dinosaurs, but they don't actually appear in the fossil record until about 50 million years ago, where we find them already having evolved powered flight and, in some species, echolocation. Scientists have debated whether bats first evolved flight or echolocation or if they evolved in tandem.

Onychonycteris is very similar to modern bats with a few key differences. It had a long rat-like tail, claws on all five digits (as opposed to modern bats who only have claws on one or two digits), and based on the skull, it probably didn't have echolocation, which would support the hypothesis that flight evolved first.

Chart with PhyloPic silhouettes from an essay in the upcoming comic book, Paleocene #4. These are lineages that survived the Cretaceous–Paleogene extinction event but died out before the Holocene Epoch (which is almost too brief to be visible here—it is a thin sliver atop the Pleistocene). Figures are not to scale, and do not line up perfectly to lineage extinction dates, just to epochs. This chart is available under the CC BY-SA 3.0 license.

Paleovember 2023, Barylambda!

This strange animal, roughly the size of a pony, was the largest known member of the pantodonts, one of the first groups of large mammals to evolve in the Paleocene, right after the extinction of the dinosaurs. Barylambda itself was the largest animal in its environment; it's powerful tail would have allowed it to rear up on two legs to reach it's preferred food of soft vegetation and other foliage. Males also possessed a pair of canines for intraspecific combat.

[pleistocene-pride]

Glaucopsyche xerces, better known as the Xerces blue butterfly or simply xerces blue is a recently extinct species of butterfly in the gossamer-winged butterfly family, Lycaenidae. The species was first described and documented in 1852, and was named after the French spelling of "Xerxes", the Greek name of the Persian kings Xerxes I and Xerxes II of the fifth century BC. Reaching around .7 to 1.18inches (18 to 30mm) in wingspan length, the xerces blue is a small, brightly colored butterfly characterized by iridescent blue on the upper wing surfaces of males, and pale spots below. It was endemic to the coastal sand dunes of the upper San Francisco Peninsula where the Xerces fed on vegetation belonging to the genus Lotus and Lupinus. The loss of the Lotus plant that the butterfly fed on while in its larval stages is believed to be the main reason for the extinction of the Xerces blue. As growing urban development resulted in extensive disturbance and loss of habitat of which the lotus plant couldn’t survive. Lupinus, the Xerces blue's other main adult food source, was not suitable for the larval stages. By the early 1940s the Xerces Blue was driven to extinction, becoming one of the first and most well-known butterflies in the United States lost due to human impact, with the last confirmed sighting of a xerces blue occurring in 1943 on land that is now part of the Golden Gate National Recreation Area. The butterfly’s extinction inspired the foundation of the Xerces Society for Invertebrate Conservation in 1971, as well as ushering the need for insect and invertebrate conservation into the public mindset. Today there are ongoing efforts to reestablish related butterflies in the Xerces blue's former habitat such as the silvery blue and the Palos Verdes blue. Also the possibility of reviving the xerces blue via de-extinction is being explored.

Love this animal, the macarena

Images nabbed from Wikipedia. Last one is by Michael Tripoli. He's a pretty cool artist to my knowledge. He's on twitter and insta btw
