Dinocember Day 8: Avisaurus
An Avisaurus is perched on a branch and is consuming a small rodent-like mammal. The mammal's body is being pinned down by the foot of the Avisaurus, similar to how some modern birds of prey hold their food. Some smaller branches and the moon can be seen in the background.

Newest watercolor is of the recently described prehistoric bird, Avisaurus darwini. Foot bones from this hawk-sized bird suggest it had strong grasping toes like modern birds of prey. Here it is with a baby Acheroraptor it captured. #paleoart #sciart #watercolor

here's today's #Paleostream flocking sketches!!!

today we drew Anhanguera, Sordes, Avisaurus, and Mawsonia
on an overcast day, a flock of Anhanguera hunt a school of fish below the surface of the ocean, a Platypterygius also hunting the school dives back below the water after taking a breath a lone Sordes flies infront of a solar eclipse an Avisaurus attacks a juvenile hell creek azhdarchid by latching onto its head mid-flight. the juvenile's thrashing only leads to lacerations on its face a juvenile polycotylid has wandered too far from the safety of the mangrove forest, a Mawsonia opens its mouth swiftly in an attempt to swallow the juvenile whole

here's today's #Paleostream flocking sketches!!!

today we sketched Triceratops, Helveticosaurus, Dickinsonia, and Melanorosaurus
a Triceratops horridus (="Nedoceratops hatcheri"?) walks through the thick underbrush, an Avisaurus uses its especially vertically oriented horns as a perch, looking out for small prey that may be spooked into the open by the giant's steps Triceratops is an elephant-sized herbivorous dinosaur famous for its large frill, two large brow horns, and one smaller nasal horn, "Nedoceratops" is a doubtful genus of ceratopsian, the supposed holotype has been altered with plaster and may have been the result of pathology, it's also been noted that it still falls within the range of individual variation of Triceratops horridus Avisaurus is an enantiornithine bird that most likely used their legs in a similar fashion to extant birds of prey on a cloudy day at the surface of the ocean, a juvenile Helveticosaurus is ambushed and flung out of the water by a Besanosaurus, its stomach has been punctured by the Besanosaurus' lower jaw Helveticosaurus is a seal-like marine reptile with a sausage-like body and long conical teeth Besanosaurus is a large macropredatory ichthyosaur that had a long and thin snout, as well as long flippers a Dickinsonia tenuis feeds on a pink microbial matt in the shallows by the shoreline, its feeding traces can be seen behind it, a smaller Dickinsonia feeds further to the back. small aysheaiids consume the left over organic matter that gathers on the large Dickinsonia's back Dickinsonia is a stem-animal that doesnt have true bilateral symmetry, D. tenuis is the largest species with some individuals measuring 1.4 metres long. they fed by consuming the microbial mat directly below its underside, however the method of which they consumed said mats is unknown Aysheaiidae is a group of small lobopodians who's only evidence of existence in the Ediacaran is trace fossils, they had two longer arms to either side of their mouth probably used for either sensing and food manipulation two Melanorosaurus bask in the morning sun Melanorosaurus is a basal sauropodomorph, and was one of the first that definitively walked quadrupedally, it looked kind of like a long necked iguana with a long snout

Las aves de este grupo eran en general pequeñas, ocupando una gran diversidad de nichos: había generalistas, granívoras, piscívoras, zancudas… La mayoría de especies se conocen de China, aunque tenían distribución mundial. Aquí algunos ejemplos:
