Bigger crown groups can also be defined, such as the phylum Chordata.

The position of hagfish in the phylum chordata is not settled.

But Chordata, some would flatter themselves, required another hundred million years of evolutionary fine-tuning.

A vertebrate is a member of the phylum Chordata.

The special position of Chordata with respect to the nervous system is shown in the very nature of the nerve cord.

Mammalia is a class of animal within the Phylum Chordata.

Some put them in the phylum Chordata, and call them calcichordates.

However, there are about 200 species from the phylum Chordata present, of which two-thirds are birds.

Conodonts are an extinct class of the phylum Chordata.

It reaches the pinnacle of its development in the Phylum80 Chordata, the one to which we ourselves belong.

Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described.

That would at least circumscribe the Chordata.

The main phyla of deuterostomes are the Echinodermata and Chordata.

After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion.

As the name suggests, craniates are animals with a (hard bone or cartilage) skull in phylum Chordata.

As eusociality became a recognized widespread phenomenon, however, it was also discovered in Chordata, specifically Rodentia.

Evolutionary origins of vertebrates as well as the phylum Chordata have not been scientifically determined.

"Invertebrata" is a term of convenience, not a taxon; it has very little circumscriptional significance except within the Chordata.

QSER1 is highly conserved in most species of the clade Chordata.
