Amarillo fosil is a â??calcarenitaâ?� rock, very homogeneous. It is dim yellow with some pink shadows, formed by fossils with carbonated main base and travertinic texture. Amarillo fosil is ideal for exteriors and, due to its particular porosity it can be easily set up with traditional cement and putty. Although it could also be placed with fixing systems without losing its resistance. It withstands brusque changes of temperature, preventing structural damages, cracks or fissures from appearing. The main finishes of amarillo fosil are: honed vein cut, honed crosscut, brushed / antique, sandblasted, bush hammered and polished pore covered coloured resin -
