With a mass of approximately 1.95 grams (0.069 oz) and a length of 5.5 centimetres (2.2 inches), the bee hummingbird (Mellisuga helenae) is the smallest known dinosaur as well as the smallest bird species, and the smallest warm-blooded vertebrate. Called the zunzuncito in its native habitat on Cuba, it is lighter than a Canadian or U.S. penny.
A nanobe (/ ˈ n æ n oʊ b, ˈ n eɪ n oʊ b /) [1] is a tiny filamental structure first found in some rocks and sediments.Some scientists hypothesize that nanobes are the smallest form of life, 1 / 10 the size of the smallest known bacteria.

Egg measures less than 30mm long
It was small enough to fit in the palm of one’s hand. ... “This species represents the smallest known fossil member of the family Felidae to date,” the study says of the newly discovered cat.
The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew, white-toothed pygmy shrew and Savi’s pygmy shrew, is the smallest known extant mammal by mass, weighing only about 1.8 g (0.063 oz) on average.
Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
The smallest known mitochondrial genome is that of Plasmodium falciparum, with a genome size of 6kb containing three protein-coding genes and a few rRNA genes. (On the other hand, the largest known mitochondrial genome is 490kb. [18]) Genomes nearly as small can be found in related apicomplexans as well. [19]
