8.67.28

taṃ somakāḥ prekṣya hataṃ śayānaṃ prītā nādaṃ saha sainyairakurvan |
tūryāṇi cājaghnuratīva hṛṣṭā vāsāṃsi caivādudhuvurbhujāṃśca |
balānvitāścāpyapare hyanṛtyannanyonyamāśliṣya nadanta ūcuḥ || 28 ||

Similarly, Krishna and Dhananjaya also, filled with delight, and losing no time, blew their conchs. The Somakas beholding Karna slain and lying on the field, were filled with joy and uttered loud shouts with the other troops (of the Pandava army). In great delight they blew their trumpets and waved their arms and garments. All the warriors, O king, approaching Partha, began to applaud him joyfully. Others, possessed of might, danced, embracing each other, and uttering loud shouts, said, "By good luck, Karna hath been stretched on the earth and mangled with arrows." Indeed, the severed head of Karna looked beautiful like a mountain summit loosened by a tempest, or a quenched fire after the sacrifice is over, or the image of the sun after it has reached the Asta hills. The Karna-sun, with arrows for its rays, after having scorched the hostile army, was at last caused to be set by the mighty Arjuna-time. As the Sun, while proceeding towards the Asta hills, retires taking away with him all his rays, even so that shaft (of Arjuna) passed out, taking with it Karna's life breaths. The death hour of the Suta's son, O sire, was the afternoon of that day. Cut off with the Anjalika weapon in that battle, the head of Karna fell down along with his body. Indeed, that arrow of Arjuna, in the very sight of the Kaurava troops, quickly took away the head and the body of Karna.
