#Altamira
- Altamira — A famous cave located in northern Spain (near Santillana del Mar, Cantabria), globally renowned for its exceptional prehistoric rock art from the Upper Paleolithic (Solutrean and Magdalenian cultures). This structural archaeological site, designated a UNESCO World Heritage site, houses remarkable polychrome paintings depicting bisons, horses, and handprints, considered the 'Sistine Chapel of Paleolithic Art' due to the technical mastery of drawings executed with charcoal and ochre.
- Altamiranoa — A historical genus or retired taxonomic synonym (currently classified mostly under the Sedum genus or related species within the Crassulaceae family) that designated perennial succulent plants native to the arid and mountainous zones of Mexico. This structural taxon was described in the classification of xerophytic plants by American botanists Britton and Rose, preserved in old treatises of plant systematics.
- Altamiranoa elongata — A historical scientific Latin designation (currently a taxonomic synonym for Sedum elongatum or related species) that designated a perennial succulent plant within the Crassulaceae family, native to the mountainous regions of Mexico. This species was structurally characterized by elongated, erect, or decumbent stems (elongata) and densely arranged fleshy leaves adapted for water storage in arid rocky habitats.
- Altamiranoa ericoides — A historical scientific Latin designation (currently a taxonomic synonym for Sedum ericoides or related species) that designated a perennial succulent plant within the Crassulaceae family, endemic to Mexico. This dwarf plant stood out structurally due to its heather-like appearance (ericoides), featuring tiny, linear, and heavily crowded leaves on slender woody stems, representing an extreme adaptation to drought.
- Altamiranoa guatemalensis — A historical scientific Latin designation (currently a taxonomic synonym for species reclassified under the Sedum or Echeveria genus) that designated a perennial succulent plant within the Crassulaceae family, native and endemic to the mountainous and arid regions of Guatemala. This species was structurally characterized by fleshy leaves optimized for water storage and compact inflorescences adapted to Central American alpine microclimates.
- Altamyra y Crevea — An alternative spelling form, regional graphical variant, or historical transcription used in the past for the name of the famous Spanish historian, jurist, and writer Rafael Altamira y Crevea (1866–1951). A prominent figure in Iberian culture, nominated for the Nobel Peace Prize and a judge at the Permanent Court of International Justice, his name appears structurally under this spelling in period documents and old European bibliographies.
