A fossorial animal (from Latin fossor 'digger') is one that is adapted to digging and which lives primarily (but not solely) underground. Examples of fossorial vertebrates are badgers , naked mole-rats , meerkats , armadillos , wombats , and mole salamanders . [ 1 ]
A-type star In the Harvard spectral classification system, a class of main-sequence star having spectra dominated by Balmer absorption lines of hydrogen. Stars of spectral class A are typically blue-white or white in color, measure between 1.4 and 2.1 times the mass of the Sun, and have surface temperatures of 7,600–10,000 kelvin.
time and star positions by observation of star transits, e.g. by meridian circles (visual, photographic or CCD) Azimuth determination for the exact orientation of geodetic networks; for mutual transformations between terrestrial and space methods; for improved accuracy by means of "Laplace points" at special fixed points
A fossorial, or burrowing, lifestyle for Simosuchus has been suggested in its initial description based on the robust limbs and short snout, which appears shovel-like, and the underslung lower jaw that would prevent friction when the animal opens its jaws during burrowing. There are also areas on the skull that may have attached to strong neck ...
Closest star to the Sun with exactly six [29] exoplanets, and closest K-type main sequence star to the Sun with a multiplanetary system. One of the oldest stars with a multiplanetary system, although it is still more metal-rich than the Sun. None of the known planets is in the habitable zone.

The American spadefoot toads are of typical shape to most fossorial (or burrowing) frogs. They are round, with short legs and protruding eyes. As suggested by their name, these frogs have hard, keratinous protrusions present on their feet, which help them to dig. Like most fossorial frogs, they dig backwards into the ground. [1]
