On April 4 the 10th season’s extra episodes of the show “The Walking Dead” ended.
The episode “A Certain Doom” was supposed to be the 10th season finale of the TV show “The Walking Dead”. Due to the Covid-19 pandemic, not only has it become a special episode broadcast six months after the previous ones but the producers decided to extend the season. In the period that the second part of a season of this show normally airs, six extra episodes aired.
An article published in the journal “Science Advances” reports a study on trilobites that offers evidence that in the upper branch of these ancient arthropods’ limbs there were gill-like structures that were used for breathing. A team of researchers led by Jin-Bo Hou of the University of California at Riverside (UCR) subjected exceptionally preserved specimens belonging to the Triarthrus eatoni and Olenoides serratus species to CT scans to study their anatomical details. The results led to their conclusion concerning the presence of gill-like structures in the upper branches of their legs which they used to breathe.
An article published in the “Journal of Vertebrate Paleontology” reports the discovery of a carnivorous dinosaur that lived about 80 million years ago in today’s Argentina. A team of researchers led by paleontologist Federico Gianechini of the National University of San Luis named it Llukalkan aliocranianus after examining a partial skull discovered in the Bajo de la Carpa Formation. The new species and the new genus have been attributed to the Furileusauria group, part of the abelisaurid family, widespread in the ancient subcontinent Gondwana. The examination of the uncovered bones suggests that it had better hearing than the other abelisaurids.
