I just love the photo, I took during our vacation to this city a couple of years ago. In this site, you will find articles from my autobiography, global warming, senior citizens issues, tourism, politics in PI, music appreciation and articles about our current experiences as retirees enjoying the "snow bird" lifestyle between US and the Philippines. Your comments will be highly appreciated. Some of the photos and videos on this site, I do not own. However, I have no intention on infringement of your copyrights. Cheers!

The Fossils Wonder of the Grand Canyon

his posting is inspired from my recent reading on the WSJ on fossils found in the Grand Canyon. I found it interesting, thus  I am sharing it with you.  

The above photo is a  striking image of the newly discovered fossil footprints—Ichniotherium trackways embedded in Coconino Sandstone—found in the Grand Canyon. These well-preserved footprints offer a rare glimpse into very early terrestrial vertebrates venturing into desert ecosystems over 280 million years ago .


Why This Discovery Matters

Recent paleontological research in the Grand Canyon has revealed findings of exceptional scientific importance:

1. First Soft-Bodied Cambrian Fossils from the Grand Canyon
— In a groundbreaking 2023 expedition along the Colorado River, researchers collected mud-rich rock samples that, when dissolved and sieved, revealed exquisitely preserved soft-bodied fossils dating back 502–507 million years ago—during the Cambrian explosion. Among the finds were mollusks, filter-feeding crustaceans, and a new species of “penis worm” named Kraytdraco spectatus Discover WildlifeScienceDailySmithsonian MagazineThe Washington PostSFGATE.

2. A “Goldilocks Zone” for Innovation
— The Grand Canyon’s ancient shallow sea environment provided a unique combination of nutrient-rich, warm, and well-oxygenated waters—not too deep, not too turbulent—creating optimal conditions for evolutionary experimentation and innovation during life's crucial early stages The Washington PostScienceDailySmithsonian Magazine.

3. The Extraordinary Kraytdraco spectatus
— This newly discovered priapulid worm sported a retractable, glove-like throat adorned with multiple rings of teeth—both robust scraping teeth and delicate feathered ones—suggesting sophisticated dual-function feeding: raking and filtering particles The Washington PostSFGATE.

4. A Window into Ancient Ecosystems
— Alongside the worm, researchers documented mollusks scraping algae, shrimplike crustaceans with hair-like feeding appendages, and traces of feeding behavior—all preserved in incredible detail. These fossils effectively reconstruct a vibrant early marine ecosystem The Washington PostSmithsonian MagazinePhys.org.

5. Older Trackways: Early Desert Dwellers
— Another noteworthy discovery is a boulder containing fossilized footprints—Ichniotherium trackways—of ancient tetrapods (diadectomorphs) from about 280 million years ago, preserved in the Coconino Sandstone. These tracks represent the youngest-known occurrence of this type and the first evidence of diadectomorphs in arid desert environments. They suggest that early vertebrates adapted to life in dry, wind-blown dune terrains, contrary to prior expectations that they required moist habitats National Park Service+2National Park Service+2.

Meanwhile, Did you know that.....
The Philippines is home to 186 individual languages! While Filipino (based on Tagalog) and English serve as the country’s official languages, several regional tongues thrive with millions of speakers—like Cebuano, Ilocano, Hiligaynon, Waray, and many more. 
This rich linguistic diversity reflects the country’s complex history and vibrant cultural identity.

Besides, Tagalog, English and a little Spanish, I speak fluent Hiligaynon (Ilonggo), the language of my birth.
