For instance, the American rootstocks have broader than larger trilobate leaves. |

The dorsal morphology of both the head shield and tergites of Leanchoilia superlata was strongly trilobate. |
|
Generally, osteolepiforms have homocercal, or even trilobate, tail fins. |

Such trilobate arrowheads are believed to be more accurate and have better penetrating power or capacity to injure than flat arrowheads. |

Note the presence of the chapel in the square tower supervised by machicolations with trilobate decorations on one side, as the shape of embrace of the other side. |
