The ichnogenus Thalassinoides: burrow fossil produced by crustaceans from the Middle Jurassic, Makhtesh Qatan, southern Israel. An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact.
In 2016 Molina-Perez and Larramendi based on the 45 cm (1.48 ft) long footprint estimated the size of the animal at 8.4 meters (27.5 ft) and 600 kg (1.323 lbs). [8] Another 60.5 cm (1.98 ft) long footprint belongs to an 8.1 meter (26.6 ft), 1.1 tonne (2.425 lbs) individual, that was very similar to Sinosaurus triassicus .
Discovery location: South Carolina, US; age: Miocene; dimensions: 144.6 mm × 63.41 mm (5.693 in × 2.496 in); weight: 558 g (1 lb 3.7 oz) Trace fossils are best preserved in sandstones; [4] the grain size and depositional facies both contributing to the better preservation. They may also be found in shales and limestones. [4]
Experts believe that the footprint was most likely left by a dinosaur (grallator) that stood about 75 centimeters (29.5 inches) tall and 2.5 meters (about 8 feet) long and walked on its two hind feet. [11] [12] The scientists called the girl's discovery "the finest impression of a 215 million-year-old dinosaur print found in Britain in a decade ...
The world-average ecological footprint in 2016 was 2.75 global hectares per person (22.6 billion in total). With a world-average biocapacity of 1.63 global hectares (gha) per person (12.2 billion in total), this leads to a global ecological deficit of 1.1 global hectares per person (10.4 billion in total).
The Human Footprint increased by 9% from 1993 to 2009, at least partly attributable to a human population increase of 23% and a global economy increase of 153% during the same period. [3] Though population and economic growth far exceed the growth of the Human Footprint, the areas that saw increased human influence were those with the highest ...

A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
