Europe's very own dinosaurs -- the enigmatic Late Cretaceous rhabdodontids      (via sciencedaily.com)     Original source 

A new study brings together intriguing details about the little-known Rhabdodontidae dinosaurs of Late Cretaceous Europe. These gregarious herbivores, characterized by robust builds and beaks specialized for tough vegetation, inhabited the European archipelago. Despite being widespread and abundant, they vanished in Western Europe due to environmental changes around 69 million years ago, while surviving longer in Eastern Europe. Their fossil record offers valuable insights into their evolution and lifestyle, although its limited nature still challenges comprehensive understanding.

Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution      (via sciencedaily.com)     Original source 

Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.

Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.

Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life      (via sciencedaily.com)     Original source 

For the first time, a group of researchers have successfully extracted ancient DNA from a 2,900-year-old clay brick. The analysis provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from other sites and time periods.

Did sabertooth tigers purr or roar?      (via sciencedaily.com)     Original source 

When a sabertooth tiger called out, what noise did it make -- a mighty roar or a throaty purr? A new study examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought -- and that it could depend on the shape of a few small bones.

Ancient metal cauldrons give us clues about what people ate in the Bronze Age      (via sciencedaily.com)     Original source 

Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).

Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima      (via sciencedaily.com)     Original source 

Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.

Vlad III, known as Vlad the Impaler, was a 15th century prince and military leader who was so terrifying, he's thought to have inspired the creation of the literary vampire, Count Dracula. Now, a scientific examination of his letters is giving new insights into his health. Researchers say the results suggest that Vlad probably had skin and respiratory conditions and could have even cried literal tears of blood.

Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells      (via sciencedaily.com)     Original source 

With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.

Ancient DNA reveals an early African origin of Cattle in the Americas      (via sciencedaily.com)     Original source 

Using ancient DNA, researchers have determined cattle were imported from Africa to the Americas much earlier in the process of European colonization than documented. The first records of African cattle in the Americas date back to the 1800s, leading some historians to conclude that early colonists relied entirely on a small stock of European cattle initially shipped to the Caribbean Islands. DNA from archaeological specimens pushes the introduction of African cattle back by more than 100 years.
