Colossal Raptor Dinosaur Possessed Legs that Surpassed your Height

The raptors depicted in the Jurassic Park films were already fearsome at six feet tall, but now researchers have identified a colossal new raptor species with legs towering to that same height.

Raptors constituted a varied array of dinosaurs resembling the iconic movie creatures, albeit varying in size. They shared a common body structure, featuring a robust snout brimming with formidable teeth and elongated, avian-like legs culminating in the distinctive, curved claw on a single toe. Paradoxically, they likely exhibited more flamboyance than portrayed in Hollywood, with prevailing beliefs suggesting that the majority, if not all, raptor species boasted feathered coverings.

A newly identified marine reptile species may have been the largest to ever inhabit the world’s oceans. Dubbed the “giant fish lizard,” this creature existed over 200 million years ago and could rival the size of the blue whale. Ichthyosaurs, a diverse group of marine reptiles from the dinosaur era, resemble a mix between a

Rare Evolutionary Event: Two Lifeforms Merge

Biology, Evolution, Science / Jorge Paka

Scientists have witnessed a once-in-a-billion-year evolutionary event where two lifeforms merge, creating an organism with enhanced abilities. The last occurrence led to the emergence of plants on Earth. Known as primary endosymbiosis, this phenomenon occurs when one microbial organism engulfs another, utilizing it as an internal organ. In return, the host cell provides nutrients, energy,

Tiny Frog’s Silent Ultrasonic Scream

Biology, Science / Jorge Paka

The Brazilian Atlantic Rainforest resounds with the high-pitched ‘screams’ of a minuscule amphibian in distress, a sound previously unnoticed by human ears. Researchers have, for the first time, captured recordings of South American frogs emitting calls at frequencies beyond human perception but potentially unsettling to animals equipped with suitable receptors. Dominance of the Leaf Litter

Newer Generations with Larger Brains are Influencing Dementia

Biology, Evolution, Neuroscience, Science / Jorge Paka

Larger brain size indicates enhanced brain health and cognitive abilities. Since the 1930s, there has been a consistent increase in brain size. A recent study highlights the implications of this growth on the likelihood of developing dementia, specifically Alzheimer’s disease. By 2020, more than 55 million people worldwide had dementia, with projections indicating a doubling
