DINOSAUR EXTINCTION VIALS ARE NOW IN STOCK!
These vials contain evidence of one of the most iconic extinction events in history - the asteroid impact that wiped out all non-avian dinosaurs! You can clearly see the dark sediment layer, known as the K-T Boundary Layer, which contains large quantities of micro-meteorites and asteroidal iridium.
Worldwide shipping is available and we are asking $20CAD (~15.50USD) per 2.5" tall vial. Buy them now on www.SkullStore.ca or in-store Thursday-Sunday (12-6pm) at 1193 Weston Rd, Toronto. ~67 million years ago a massive asteroid slammed into the Gulf of Mexico, carving out a 180km wide crater and plunging the world into darkness. The shockwaves tore across the Earth and its atmosphere, instantly killing off most lifeforms.
Tsunamis tore apart coastal ecosystems, washing away and drowning countless dinosaurs and other animals.
This was only the beginning - those who survived the initial onslaught, likely deafened and disoriented, would have watched as their world caught fire. Burning/molten meteoric fragments and Earth rock (launched into space by the impact) fell back to the surface, killing anything they struck and igniting vegetation. This hellfire is known scientifically as "tektites". The dust and smoke choked the skies, turning day to night. The resulting cooling and lack of UV killed off much of the world's vegetation, causing catastrophic collapses of the world's food chains.
If you couldn't fly or burrow, the chances of surviving as a terrestrial animal were almost non-existent. 75% of all species on Earth were entirely eradicated, opening the door for a group of small, fur-bearing, animals - known as mammals - to rise from the ashes and achieve dominance of the world.
This is an Australopithecus Afarensis, named Salem, who walked the plains of Eastern Africa 3.8 - 2.9 million years ago. She stands less than 3 feet tall. About 4 million years ago, the climate became drier. Forests turned to grasslands. Fossil tooth enamel from Salem shows a shift from a diet of leaves and fruit to a diet of roots, insects, meat and mushrooms. This diet was easier to digest, so energy once used for digestion could have been used to increase brain size.
Happy National #PublicLandsDay[email protected] continues their Instagram takeover this week to share 22 reasons to love the Grand Staircase-Escalante National Monument on its 22nd anniversary (reasons 17-22 below). Share YOUR reasons you want @usinterior and @mypubliclands to keep Grand Staircase-Escalante intact using the hashtags #SaveGrandStaircase and #MonumentsForAll.
17. Per capita income in the Grand Staircase-Escalante region experienced a 17% increase from 2001-2015. National Monuments are good for their gateway communities!
18. The Grand Staircase-Escalante National Monument currently has the only BLM Paleo lab in the United States (you're up next, Bears Ears!) 19. Protected Federal Lands Benefit Rural Western Counties - A 2014 study by Headwaters Economics found that Western non-metropolitan counties with more than 30 percent of the county's land base in federal protected status such as national parks, monuments, wilderness, and other similar designations increased jobs by 345 percent over the last 40 years. By comparison, similar counties with no protected federal public lands increased employment by 83 percent.
20. Archaeological findings in the Grand Staircase-Escalante National Monument represent some of the oldest evidence of human habitation on the Colorado Plateau, and are challenging what we know about technology, food cultivation and trade patterns of its earliest inhabitants.
21. Monuments Benefit Small Business - A study by Small Business Majority finds that the 10 natural and cultural monuments protected by President Obama are responsible for $156.4 million in annual economic benefits for local communities, with national monument visitation resulting in approximately $58 million in labor income and supporting 1,820 jobs. Further, the study finds that this economic activity is particularly beneficial to small businesses in these predominantly rural communities.
22. Last year, more than 1 million people from all over the world visited Grand Staircase-Escalante to enjoy the vast, unspoiled landscape for themselves.
Species: Velociraptor mongoliensis
Temporal Range: Late Cretaceous
Diet: Carnivorous (scavenger)
Length 2.1 meters
Despite depictions of this dinosaur in popular culture, Velociraptor is only waist high on an average human male, had thick plumage, and wasn’t the most intelligent dinosaur. However, this animal did hunt in packs and may have acted not only as a Prehistoric hawk, but a vulture as well, feeding off of carrion. The most famous fossils have a velociraptor and a protoceratops locked in combat! From this we know that the switchblade like claw on the middle toe was used to hang on to and tear out the windpipe of potential prey. #extinctiondoesnthavetobeforever#paleontology#dinosaurs#dinosaurday#dinosaur#prehistoric#prehistory#lifefindsaway
This unusual large mammal lived in North America during the
Pleistocene epoch until the end of the ice age. It roamed the earth
for over a million years, but suddenly disappeared (perhaps because of the climate changes). It was one of the largest land animals living during the ice age. Mastodon belonged to the family Mammutidae, that originated in North Africa, spreading to Eurasia and entering North America 15 million years ago. Its name means "nipple tooth". These elephant-like animals were affected by environmental changes. Mastodons living during the middle of the last glaciation were small, whereas those living later in forests were larger. It was mostly adapted to conifer forests and marsh. It fed on plants (conifer twigs, swamp plants, larch, spruce, pine, grass, mosses, etc.) and used its tusks to break branches.
