The 165-million-year-old fossil of Microdocodon gracilis, a tiny, shrew-like animal, shows the earliest example of modern hyoid bones in mammal evolution.
A collaborative research project carried out under the auspices of the GeoBio-Center at Ludwig-Maximilians-Universitaet (LMU) in Munich has developed an integrative approach to the classification of fossil cichlids, and identified the oldest known member of the Tribe Oreochromini.
New research brings to light for the first time the evolution of maternal roles and parenting responsibilities in one of our oldest evolutionary ancestors. Australopithecus africanus mothers breastfed their infants for the first 12 months after birth, and continued to supplement their diets with breastmilk during periods of food shortage. Tooth chemistry analyses enable scientists to 'read' more than two-million-year-old teeth. Finding demonstrates why early human ancestors had fewer offspring and extended parenting role.
Researchers from the National Museums of Kenya, University of Arkansas, University of Missouri and Duke University have announced the discovery of a tiny monkey that lived in Kenya 4.2 million years ago.
Mount Sinai researchers working as part of an international team have discovered previously unknown breastfeeding patterns of an extinct early human species by studying their 2-million-year-old teeth, providing insights into the evolution of human breastfeeding practices, according to a study published in Nature in July.
Auroraceratops, a bipedal dinosaur that lived roughly 115 million years ago, has been newly described by an international team of researchers led by paleontologist Peter Dodson of the University of Pennsylvania and former student Eric Morschhauser, now of Indiana University of Pennsylvania. More than 80 individuals of this species have been found in China's Gansu Province.
A team of paleontologists led by Professor Jingmai O'Connor from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, together with researchers from the Shandong Tianyu Museum of Nature, have discovered a new specimen of the volant dromaeosaurid Microraptor zhaoianus with the remains of a nearly complete lizard preserved in its stomach.
Meet the ancient bird that had toes longer than its lower legs. Researchers have discovered a bird foot from 99 million years ago preserved in amber that had a hyper-elongated third toe. The study, published in the journal Current Biology on July 11, 2019, suggests that this bird might have used its toes to hook food out of tree trucks. This is the first time such a foot structure has been observed in birds.
Peptides, one of the fundamental building blocks of life, can be formed from the primitive precursors of amino acids under conditions similar to those expected on the primordial Earth, finds a new UCL study published in Nature.
Hox gene do not work alone to determine the layout of vertebrae, limbs and other body parts. A study led by University of Pittsburgh researchers shows how an entire network works together toward that goal.
