Classes e generes fossile:

Chordata (chordates o chordatos) es un phylo animal characterisate per le presentia de un chorda neural tubular dorsal o notochorda, sia durante tote le disveloppamento, sia in alicunes del phases de lor vita. Il ha tres subphylos: Cephalochordata, Tunicata e Vertebrata.

Definition[modificar | modificar fonte]

1 = cerebral protuberantia
4 = coda post-anal
5 = ano
9 = spatio suprapharyngee


11 = pharynge
12 = vestibulo
13 = oral cirros
14 = apertura buccal
16 = sensor de lumine
17 = nervos
19 = hepatic ceco (protohepate)

Le chordatos forma un phylo — un gruppo de animales con un commun plan del corpore[5] — organismos que ha tote le sequente:[6]
