Scientists Identify Tylosaurus Rex as Distinct Marine Predator from Cretaceous Period

Scientists Identify Tylosaurus Rex as Distinct Marine Predator from Cretaceous Period

Scientists have identified Tylosaurus rex as a distinct species of marine reptile that lived during the Cretaceous Period, approximately 80 million years ago. This discovery was made after a comprehensive examination of previously discovered fossils, which revealed unique anatomical features such as fine serrations on the teeth and strong jaw musculature. Tylosaurus rex, a member of the mosasaur family, was a formidable predator in the Western Interior Seaway of North America, rivaling the land-dwelling Tyrannosaurus rex in size and ferocity. The largest known specimen, nicknamed Bunker, measures about 43 feet in length and is housed at the University of Kansas Biodiversity Institute and Natural History Museum.

New Mosasaur Species Identified in Texas, Redefining Prehistoric Marine Predators

New Mosasaur Species Identified in Texas, Redefining Prehistoric Marine Predators

Scientists have identified a new species of mosasaur, Tylosaurus rex, from fossils found in northern Texas. This massive marine reptile, which lived about 80 million years ago, was one of the largest and most aggressive of its kind. The discovery was made by researchers from the American Museum of Natural History, Dallas' Perot Museum of Nature and Science, and Southern Methodist University. The findings suggest that some museum specimens may have been misclassified, prompting a reevaluation of existing collections.

New Prehistoric Reptile Species Discovered in New Mexico Offers Insights into Evolution

New Prehistoric Reptile Species Discovered in New Mexico Offers Insights into Evolution

Scientists have identified a new prehistoric reptile species, Labrujasuchus expectatus, from fossils found in a Triassic quarry in New Mexico. This species, which lived approximately 212 million years ago, is a distant relative of modern crocodiles. Unlike its relatives, it had a beak, no teeth, and tiny arms, and walked on two hind legs. The discovery was made by a team led by Alan Turner, a professor of anatomical sciences at Stony Brook University. The findings, published in the Journal of Vertebrate Paleontology, highlight subtle differences that distinguish this species from other North American shuvosaurids.

Fearsome dinosaur-era marine reptile was the T. rex of the sea

Fearsome dinosaur-era marine reptile was the T. rex of the sea

By Will Dunham May 28 (Reuters) - Tyrannosaurus rex was a huge land predator during the twilight of the age of dinosaurs. But it was not the only T. rex that terrorized the Cretaceous Period.

Sea Cucumber Tissue Shows Signs of 'Immortality,' Offering New Research Model

Sea Cucumber Tissue Shows Signs of 'Immortality,' Offering New Research Model

Researchers have discovered that severed body parts of the sea cucumber species Psolus fabricii can survive and function independently for over three years. These tissue fragments, referred to as 'zombies,' maintain cellular function without developing into new organisms. The study, published in Science Advances, highlights the potential of these tissues to serve as a model for medical research, particularly in understanding tissue repair and aging. The fragments were observed to heal themselves and absorb nutrients without a mouth, challenging traditional notions of what it means to be alive.

New Octopus Species Discovered in Galápagos Highlights Deep-Sea Biodiversity

New Octopus Species Discovered in Galápagos Highlights Deep-Sea Biodiversity

Scientists have identified a new species of octopus, Microeledone galapagensis, discovered in the Galápagos Islands. The tiny, blue octopus was found nearly 6,000 feet below the ocean surface and resembles a plush toy. The discovery was made by a team aboard the E/V Nautilus in collaboration with the Charles Darwin Foundation and the Galápagos National Park Directorate. The octopus was studied using CT scanning technology at the Field Museum in Chicago, allowing researchers to examine its anatomy without damaging the delicate specimen. This discovery adds to the understanding of deep-sea biodiversity and the evolutionary history of octopuses.

Paleontologists Uncover Ancient Crocodile Relative in New Mexico, Shedding Light on Triassic Evolution

Paleontologists Uncover Ancient Crocodile Relative in New Mexico, Shedding Light on Triassic Evolution

Paleontologists in New Mexico have discovered a new species of reptile, Labrujasuchus expectatus, which lived 212 million years ago during the Triassic period. This creature, a relative of modern crocodiles, was bipedal and had a toothless beak, resembling a small dinosaur. The discovery was made at Ghost Ranch, a significant fossil site in northern New Mexico. Labrujasuchus is part of the Shuvosauridae group, known for their beaked, bipedal forms. This finding highlights the diversity and experimentation in body forms during the early stages of vertebrate evolution, particularly among proto-crocodiles.

Ancient bird's long tail feathers were perfect for a mating dance

By Will Dunham May 27 (Reuters) - New Guinea's tropical rainforests are home to one of the animal kingdom's most spectacular courtship rituals, with male birds of paradise prancing about and showing off their plumage, hoping to attract a female.

Reevaluation of Fossils Reveals Mistake in Earliest Animal Identification

Reevaluation of Fossils Reveals Mistake in Earliest Animal Identification

A team led by paleontologist Bruno Becker-Kerber has reexamined fossils from the late Ediacaran Tamengo formation in Brazil, initially thought to be the oldest evidence of meiofauna. Using advanced techniques like micro- and nanotomography, the team determined that these fossils are not traces of meiofauna but rather microbial body fossils. The study, published in Gondwana Research, found that the filaments were consistent with pyritized filamentous organisms, likely remains of red or green algae, sulfur-oxidizing bacteria, and cyanobacteria. This reevaluation corrects the previous assumption that these fossils represented ancient meiofauna, highlighting the importance of advanced technology in paleontological research.

Scientists Discover New Blue Octopus Species Near Galapagos Islands

Scientists Discover New Blue Octopus Species Near Galapagos Islands

A team of scientists from the Charles Darwin Foundation has discovered a new species of blue octopus approximately 5,900 feet underwater near the Galapagos Islands. The octopus, named Microeledone galapagensis, was first sighted in 2015 near Darwin Island. This discovery was led by octopus expert Janet Voight, who has been studying octopus evolution for four decades. The octopus is notable for its small size, unique blue hue, and distinct physical characteristics, such as stubby arms with a single row of suckers. The research, published in the journal Zootaxa, highlights the octopus's adaptation to its deep-sea environment, including its coloration, which may help it avoid predators.

Sea Cucumber Tissue's Longevity Could Revolutionize Biomedical Research

Sea Cucumber Tissue's Longevity Could Revolutionize Biomedical Research

Researchers have discovered that tissue from a sea cucumber can survive and grow for over three years in natural seawater, challenging previous assumptions about tissue immortality. This study, led by scientists at Memorial University of Newfoundland and published in Science Advances, documented the long-term viability of amputated sea cucumber tissue outside of a controlled environment. The findings suggest that this tissue can heal and grow in a complex, microbially diverse environment, absorbing nutrients directly from seawater. This discovery opens new possibilities for biomedical research, offering a model for tissue regrowth and antimicrobial healing without the ethical and logistical challenges associated with human or vertebrate cell lines.
