A fossil of the winged-seed, Alasemenia, sourced from the Jianchuan mine in Xinhang Town, China. Credit: Deming Wang Researchers have uncovered a new plant seed fossil called Alasemenia, which is among the earliest known examples of a winged seed. Researchers have uncovered one of the earliest known examples of a winged seed, providing valuable insights into the origins and early evolution of wind dispersal strategies in plants. The study, recently published in eLife, details the second-earliest known winged seed – Alasemenia – from the Late Devonian epoch, roughly 360–385 million years ago. The authors use what the editors call solid...

The ancient forest displayed traces of early plants, with some believed to have existed during the time of dinosaurs. The region's cartography commenced half a decade ago, dating back to 2019. Researchers have discovered the planet's most ancient forest within a deserted quarry near Cairo, New York. Embedded in rocks dating back 385 million years, these fossils preserve the petrified roots of numerous ancient trees. This discovery signifies a pivotal moment in Earth's timeline. As trees developed these roots, they played a crucial role in extracting carbon dioxide (CO2) from the atmosphere, sequestering it and triggering a significant transformation in...

WASHINGTON (Reuters) - A revelatory cache of fossils dug up in central Colorado details as never before the rise of mammals from the post-apocalyptic landscape after an asteroid smacked Earth 66 million years ago and annihilated three-quarters of all species including the dinosaurs. The fossils, described by scientists on Thursday, date from the first million years after the calamity and show that the surviving terrestrial mammalian and plant lineages rebounded with aplomb. Mammals, after 150 million years of subservience, attained dominance. Plant life diversified impressively. With dinosaurs no longer eating them, mammals made quick evolutionary strides, assuming new forms and...

Paleobotanists exploring a site near the Dead Sea have unearthed a startling connection between today's conifer forests in the Southern Hemisphere and an unimaginably distant time torn apart by a global cataclysm. Exquisitely preserved plant fossils show the podocarps, a group of ancient evergreens that includes the massive yellowwood of South Africa and the red pine of New Zealand, thrived in the Permian period, more than 250 million years ago. That's tens of millions of years earlier than thought, and it shows that early podocarps survived the "great dying" at the end of the Permian, the worst mass extinction the...

Researchers hope to use the fernlike Azolla to reverse the global warming effects of burning fossil fuelsJuly 15, 2014 Fifty-five million years ago, when scientists believe the Earth was in a near-runaway state, dangerously overheated by greenhouse gases, the Arctic Ocean was also a very different place. It was a large lake, connected to the greater oceans by one primary opening: the Turgay Sea. When this channel closed or was blocked nearly 50 million years ago, the enclosed body of water became the perfect habitat for a small-leaved fern called Azolla. Imagine the Arctic like the Dead Sea of today:...

Oct 30, 2009 — “Plant fossils give first real picture of earliest Neotropical rainforests,” announced a press release from University of Florida. The fossils from Colombia show that “many of the dominant plant families existing in today’s Neotropical rainforests – including legumes, palms, avocado and banana – have maintained their ecological dominance despite major changes in South America’s climate and geological structure.” The team found 2,000 megafossil specimens from the Paleocene, said to be 58 million years old. This is only 5 to 8 million years after the extinction of the dinosaurs according to conventional dating. “The new study provides...

Researchers are recovering beautiful fossils from the Cerrejón Formation of Colombia. One was a giant snake, called the “Titanoboa.” Most recently, a study examined the formation’s fossilized flora, which looked the same as modern plants, and the rainforest environment in which they lived.[1] This research dovetails nicely with other studies on ancient earth’s turbulent climate. There is evidence of dramatic...

New Fossil Cache Shows Plants Haven't Changed A coal mine in the Cerrejón Formation of Columbia has yielded a gold mine of fossils. This particular cache preserved a time in earth history when the tropical climate was quite different from today’s. Evidence indicates that it was warmer and wetter. But despite the different climate, the fossilized tropical plants were the same as today’s, albeit less diverse.The fossils reveal that ancient rainforests “were composed of the same plant families that now thrive in rainforests.†Even more remarkable, supposedly ancient fossil leaves—some of them very well preserved—were identifiable “down to the genus...

Newsweek magazine recently published a commentary by atheist Richard Dawkins containing some of his arguments against “creationists.” Therein he admitted, “What would be evidence against evolution, and very strong evidence at that, would be the discovery of even a single fossil in the wrong geological stratum.”[1] Out of place fossils are actually common, despite Dawkins’ claims regarding the “massive numbers” of fossils documenting evolutionary history. ICR News has reported on several over the last 12 months [2,3,4,5,6] and another one has surfaced recently...
