New dinosaur: First freshwater mosasaur discovered

  • PDF
A new mosasaur species discovered in Hungary is the first known example of this group of scaled reptiles to have lived in freshwater river environments similar to modern freshwater dolphins.

The research is published Dec. 19 in the open-access journal PLOS ONE by Laszlo Makadi from the Hungarian Natural History Museum, Hungary and colleagues from the University of Alberta, Canada and MTA-ELTE Lendület Dinosaur Research Group, Hungary.

The species lived about 84 million years ago, the largest specimens reached about 20 feet in length, and belongs to a family called 'mosasaurs', conventionally thought of as gigantic finned marine lizards, similar and perhaps even related to present day monitor lizards. The researchers...

How Do Fossils Form?

  • PDF
Fossils are the remains or imprints left behind from plants and animals. They can be whole parts of an animal, or just pieces of their remains. They can also include movement remnants of animals, such as footprints or imprints. In order for a fossil to form, an animal or plant must be trapped into a material. In many instances, fossils are found in sediment. Layers of sediment will envelop the remains; this can continue for thousands of years. The actual remains that are found aren't...

9.2-million-year-old rhino skull preserved by instant 'cooking to death' in volcanic ash

  • PDF
 Less than 2% of Earth's fossils are preserved in volcanic rock, but researchers have identified a new one: the skull of a rhino that perished in a volcanic eruption 9.2 million years ago.

 

The find is described in a paper published Nov. 21 in the open access journal PLOS ONE by Pierre-Olivier Antoine and colleagues from the University of Montpellier, France.

The fossil, found in Turkey, is thought to be that of a large two-horned rhino common in the Eastern...

Oldest fossil of giant panda family discovered

  • PDF
New fossils found in Spain are thought to be of the oldest recorded ancestor of the giant panda.

The fossils reveal the origins of this unique bear, as described in a paper published Nov. 14 in the open access journal PLOS ONE by Juan Abella and colleagues from the National Museum of Natural Sciences and the Catalan Institute of Paleontology, Spain.

The two 11.6 million-year-old fossil jaws and teeth were discovered in southwest Europe and represent a new genus likely to be the...

1 100-million-year-old spider attack fossil



The only fossil ever discovered of a spider attack on prey caught in its web – a 100 million-year-old snapshot of an engagement caught in amber.

The extraordinarily rare fossils are in a piece of amber that preserved this event in remarkable detail. This spider lived in the Hukawng Valley of Myanmar in the Early Cretaceous – between 97-110 million years ago – almost certainly with dinosaurs wandering nearby.

Mayfly with springtail hitchhiker: Amber specimen -- 16 million years old -- reveals unknown animal behaviors

  • PDF
Stunning images, including video footage, from a CT scan of amber have revealed the first evidence of any creature using an adult mayfly for transport.

Researchers at the University of Manchester say this 16-million-year-old hitchhiker most likely demonstrates activity that is taking place today but has never previously been recorded.

Entombed in amber the tiny springtail can be seen resting in a v-shaped depression at the base of one of the mayfly's wings. It appears to have...

Unique ancient spider attack preserved in amber

  • PDF
Researchers have found what they say is the only fossil ever discovered of a spider attack on prey caught in its web -- a 100 million-year-old snapshot of an engagement frozen in time.

 

The extraordinarily rare fossils are in a piece of amber that preserved this event in remarkable detail, an action that took place in the Hukawng Valley of Myanmar in the Early Cretaceous between 97-110 million years ago, almost certainly with dinosaurs wandering nearby.

Gold-plated fossil solution

  • PDF
1000pa (May 22, 2012) — An international team of scientists in the University of Leicester's Department of Geology has found a solution to a research problem involving fossils right next door -- in the University's Chemistry Department.

Many objects, including fossils, can reveal a huge amount of scientific information when studied using the high power magnification of electron microscopes, but in order to study tiny fossils or microscopic details of larger fossils in this way...
