Some examples of tRNA 3D structures are listed below.
Note, that in some cases anticodon loop of tRNA is colored to clarify it's disposition.
The RNAs native secondary structures were taken from: Sprinzl M., Dank N., Nock S., Schon A. Compilation of tRNA sequences and sequences of tRNA genes. Nucleic Acids Res., 1991, v. 19, suppl., p. 2127-2171.
