Mishneh Torah — Transmission of the Oral Law מסירת תורה שבעל פה, Chapter 28

וְחִבְּרוּ חַכְמֵי מִשְׁנָה חִבּוּרִין אֲחֵרִים, לְפָרַשׁ דִּבְרֵי הַתּוֹרָה: רִבִּי הוֹשַׁעְיָה תַּלְמִידוֹ שֶׁלְּרַבֵּנוּ הַקָּדוֹשׁ, חִבַּר בֵּאוּר סֵפֶר בְּרֵאשִׁית. וְרִבִּי יִשְׁמָעֵאל פֵּרַשׁ מֵאֵלֶּה שְׁמוֹת עַד סוֹף הַתּוֹרָה, וְהוּא הַנִּקְרָא מְכִלְּתָא; וְכֵן רִבִּי עֲקִיבָה חִבַּר מְכִלְּתָא. וַחֲכָמִים אֲחֵרִים אַחֲרֵיהֶם חִבְּרוּ מִדְרָשׁוֹת. וְהַכֹּל חֻבַּר קֹדֶם הַתַּלְמוּד הַבַּבְלִי.

The Sages of the Mishnah also composed other texts to explain the words of the Torah. Rabbi Hoshaia, the disciple of Rabbenu Hakadosh, composed an explanation of the book of Genesis. Rabbi Yishmael [composed] an explanation beginning at "These are the names" [the beginning of the book of Exodus,] until the conclusion of the Torah. This is called the Mechilta. Rabbi Akiva also composed a Mechilta. Other Sages of the following generations composed other [collections of the] interpretations [of verses] (Medrashim). All of these works were composed before the Babylonian Talmud.
