The primitive pulp tenia with more brazos, show a new studio – 09/03/2022 – Science / Brazil

Approximately 300 specimens of pulp cones that inhabit the oceans of the world, having brazos is a definite characteristic. But I don’t know how to do it.

The centenarians dieron el martes that a fossil desenterrado in the center of montana de especie llamada Syllipsimopods biden representa al pariente más antiguo conocido de los pulpos aktuales y tiene diez brazos, dos de los cuales son el doble de largos que los otros ocho.

The fossil is well preserved, which reveals the parallels of filas parallels of winds in each country, data on the input of 328 million years.

Oh Syllipsimopods, the entrance 12 centimeters long, I have a body in the shape of a torpedo and the squatting of a squid, but it is not really related to the squid, which is very much more expensive. Also, the creature has more anthoa conocida con ventosas, which allows its brazos agarren mejor a sus presas y otros objetos.

“The fossil is in the midst of our great understanding of how evolving the pulp and indication that the first members of the group are superficially superior to squid,” said paleontologist Christopher Whalen, a postdoctoral researcher at the York Museum of Natural History. Yale University. author of the studio, published in the Nature Communications magazine.

Blending bodies of normal pulpies do not stop fossilization, which complicates the study of animal evolution.

Los pulpos, que van desde el pulpo pygmeo cupador de 1 pulgada hasta el pulpo gigante del Pacifico de 30 pies, son conocidos por su apariencia de otro mundo, con cabezas bulbosas, ojos grandes y mandíbulas en form de pico.

They are experts in camouflage (color change and include textures to imitate on the ground) and can handle your bodywork in beautiful and beautiful colors. Tambien is also capable of using hernia and resolver problems.

“The pulpies are the most intelligent invertebrates and are found among the most intelligent animals in general. It’s fascinating to see where evolutionary animals are, ”said Whalen.

Oh Syllipsimopods There are 82 million years of oranges from a group of vampire llamas, which include the hops in the day and one of the vampire squid spies of the world.

The word “pulp” in English, “octopus”, signifies the subway and the middle. Oh Syllipsimopods represents the single member of the pulp line with these brazos, which signifies that they are lost in the evolution of posterior.

Hay numerosos ejemplos similares en la historia de la vida en la Tierra, como la reducción en el numero de dedos de los pies que se observa en los dinosaurios carnivoros o los caballos.

The squid vampire de hoy tienen ocho brazos and dos filamentos delgados que los científicos han considerado durante mucho tiempo vestigios de brazos antiguos. The pulps do not have these filaments.

“Oh Syllipsimopods he is the first fossil to be deceived that, yes, los vampiropodos tenian antepasados ​​de diez brazos, como se había predicho », dijo Whalen.

Dos de los brazos de Syllipsimopods tenian intake 3.8 cm long, and other eyes also have the size of this tamaño, in a configuration similar to that of a squid.

“The capture of the press is facilitated by the most tentacles of the world, with the eyes of most brothers who help to manipulate the press and play the pico”, said the co-author of the studio Neil Landman, paleontologist of invertebrates at the American Museum of History Natural. .

Oh Syllipsimopods live in the waters of a tropical basin: Montana is currently located near the ecuador. Pudo has a medium level spreader, which is almost inverted.

Los pulpos son cefalópodos, un grupo de invertebrados marinos que datan de unos 530 millones de años y se distinguen por tener brazos o tentáculos. The cephalopods of this include calamari, sepia and nautilus.

Oh Syllipsimopods vivió en el periodo Carbonífero, una epoca de importantes cambios evolutivos en otras formas de vida marina que influyeron la aparición de peces de aspecto más moderno.

Syllipsimopods significa «pie prensil» —sus brazos son una modificación evolutivava del pie del molusco — y biden Honra al presidente estadounidense Joe Biden, quien acababa de prestar juramento cuando se presento el estudio para su publikación.
