Reference for Zevachim 8:5

אֵבָרִין בְּאֵבְרֵי בַעֲלֵי מוּמִין, רַבִּי אֱלִיעֶזֶר אוֹמֵר, אִם קָרֵב רֹאשׁ אַחַד מֵהֶן, יִקְרְבוּ כָל הָרָאשִׁין. כַּרְעוֹ שֶׁל אַחַד מֵהֶן, יִקְרְבוּ כָל הַכְּרָעָיִם. וַחֲכָמִים אוֹמְרִים, אֲפִלּוּ קָרְבוּ כֻלָּם חוּץ מֵאַחַד מֵהֶן, יֵצֵא לְבֵית הַשְּׂרֵפָה:

[If] limbs [became mixed up] with the limbs of blemished animals, Rabbi Eliezer says: If one of their heads was offered, all of the heads may be offered; if one of their legs was offered, all of the legs may be offered. And the Sages say: Even if all but one of them was offered, the remaining one is taken out to the place of ashes.
