Palaeontologists have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts -- it's all down to their skin. Palaeontologists studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil frogs is due to preservation of ancient skin remnants ..read more

Ice age climate analysis reduces worst-case warming expected from rising CO2
ScienceDaily | Paleontology News
by
5d ago
A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely ..read more

Genetic variant identified that shaped the human skull base
ScienceDaily | Paleontology News
by
5d ago
Researchers have identified a variant in the gene TBX1 as key in the development of the unique morphology at the base of the skull. TBX1 is present at higher levels in humans than in closely related hominins. Low TBX1 also occurs in certain genetic conditions causing altered skull base morphology. This study provides a greater understanding of human disease and evolution ..read more

Interspecies competition led to even more forms of ancient human -- defying evolutionary trends in vertebrates
ScienceDaily | Paleontology News

Competition between species played a major role in the rise and fall of hominins -- and produced a 'bizarre' evolutionary pattern for the Homo lineage -- according to a new study that revises the start and end dates for many of our early ancestors ..read more

Seed ferns: Plants experimented with complex leaf vein networks 201 million years ago
ScienceDaily | Paleontology News
by
1w ago
According to a research team led by palaeontologists, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the fossilized plant Furcula granulifer was identified as such an early forerunner. The leaves of this seed fern species already exhibited the net-like veining in the late Triassic (around 201 million years ago ..read more

Digging up new species of Australia and New Guinea's giant fossil kangaroos
ScienceDaily | Paleontology News
by
1w ago
Palaeontologists have described three unusual new species of giant fossil kangaroo from Australia and New Guinea, finding them more diverse in shape, range and hopping method than previously thought. The three new species are of the extinct genus Protemnodon, which lived from around 5 million to 40,000 years ago -- with one about double the size of the largest red kangaroo living today ..read more

3D mouth of an ancient jawless fish suggests they were filter-feeders, not scavengers or hunters
ScienceDaily | Paleontology News
by
2w ago
Early jawless fish were likely to have used bony projections surrounding their mouths to modify the mouth's shape while they collected food. Experts have used CT scanning techniques to build up the first 3D pictures of these creatures, which are some of the earliest vertebrates (animals with backbones) in which the mouth is fossilized. Their aim was to answer questions about feeding in early vertebrates without jaws in the early Devonian epoch -- sometimes called the Age of Fishes -- around 400 million years ago ..read more

Do some mysterious bones belong to gigantic ichthyosaurs?
ScienceDaily | Paleontology News
by
2w ago
Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale ..read more
