2. **Identifying the Progenitors**: Seed ferns originated from pro-gymnosperms. Pro-gymnosperms are an ancient group of seedless vascular plants that show characteristics of both ferns and gymnosperms.

3. **Geological Time Frame**: The pro-gymnosperms first appeared during the Devonian period. This period is crucial as it sets the stage for the evolution of seed ferns.

4. **The Carboniferous Period**: Seed ferns specifically originated at the end of the Carboniferous period. The Carboniferous period is known for its lush vegetation and is part of the Paleozoic era.

5. **Conclusion**: Therefore, the correct answer to the question "Seed ferns originated in" is the Carboniferous period.
