This new species belongs to a group of animals called
synapsids.
I also knew you'd reject having
a synapsid for an ancestor, but you do.
The pelycosaurs were smallish to large (up to 3 meters or more) primitive Late Paleozoic
synapsid reptiles.
The pelycosaur group died out at the end of the Permian, but another group of
synapsids, the cynodonts, went on to give rise to the mammals eventually.
«We have identified footprints of pelycosaurs, a group of
synapsids that could reach four metres in length and which, in some cases, featured a sail along the spine whose function we do not know,» explains Dr Mujal.
They have also found
synapsids, the precursors of present - day mammals.
With Kenneth Angielczyk at the Field Museum of Natural History in Chicago, he found many
synapsids were most active at night.
Dinosaurs only appeared 240 million years ago, so it's unlikely
the synapsids became nocturnal to avoid being eaten.
When mammals appeared 100 million years later, they may have inherited their nocturnal ways from
synapsids.
Mammals don't have this ring, but it was present in the mammal - like reptiles or «
synapsids» they evolved from.
But if there is a direct link between nocturnality in early
synapsids and mammals, we may have misunderstood why mammals adapted to night life.
He thinks
synapsids, too, probably used cover of darkness to kill, not to escape being killed.
So Lars Schmitz at the W.M. Keck Science Department in Claremont, California studied the bony rings of 300 - million - year - old
synapsid fossils.
In fact many nocturnal
synapsids were top predators, like Dimetrodon, a 4.5 - metre beast with a prominent fin on its back.
Dimetrodon was
a synapsid, sometimes called a proto - mammal or a mammal - like reptile.
In many vertebrates, ranging from fish to early
synapsids (ancestors of mammals), denticles are commonly found in dense concentrations on the bones of the hard palate (roof of the mouth).
The early Triassic (approx. 230 mya) herbivore Kannemeyeria was the size of an ox.4 Another, earlier herbivore, Moschops of the late Permian (approx. 260 mya), was even bigger — 16 feet long.5 Contemporary with Moschops were smaller, doglike, carnivorous
synapsids (Lycaenops) with long canine teeth and running legs.
Certainly, many different kinds of
synapsids are known.
There is a vast diversity of additional groups of fossil vertebrates, including: (1) crocodilians and their extinct pseudosuchian kin; (2) marine reptiles such as plesiosaurs, ichthyosaurs, placodonts, and the like; (3) lepidosaurs (snakes, lizards, mosasaurs, tuataras, and their extinct relatives); (4) other fossil reptiles; (5) the extinct
synapsid ancestors and relatives of mammals; and (6) amphibian - grade animals such as lepospondyls, temnospondyls, and seymouriamorphs (Benton 2014).
The reptiles were mainly
synapsids (Pelycosaurs and Therapsids) that appeared in the Upper Carboniferous, and were bulky, cold - blooded animals with small brains Towards the very end of the Permian the first archosaurs appear, the ancestors of the soon to follow Triassic dinosaurs.
This will be followed by Karen Tang's artist talk about current sculpture commission, «
Synapsid».
Wall Street International published an article about Karen Tang and her «
Synapsid», the first commission of «Sculpture At Bermondsey Square» launched by Vitrine.
The Plymouth Herald have published a further piece covering the move of Karen Tang's VITRINE - commissioned sculpture «
Synapsid» to KARST, Plymouth in an article published in their Friday edition.
The Plymouth Herald have have covered the move of Karen Tang's VITRINE - commissioned sculpture «

Like other non-mammalian
synapsids, therocephalians are described as mammal - like reptiles, although in fact, Therocephalia is the group most closely related to the cynodonts, which gave rise to the mammals.
