Inside Colossal Biosciences’ Dallas HQ: The Science Behind the Woolly Mammoth Revival

D Magazine gained exclusive access to the 55,000-square-foot Dallas facility, where IVF work for the mammoth surrogate program is already underway and a 30,000-square-foot avian expansion is planned.

Colossal has opened its doors. D Magazine was granted exclusive access to the company’s 55,000-square-foot Dallas headquarters, where teams are advancing woolly mammoth gene-editing, DNA preservation, and cellular engineering, all consolidated from previously dispersed locations under one roof.

The mammoth editing phase is nearly complete. CEO Ben Lamm says IVF and ovum retrieval are already underway for the surrogate program, with the 2028 birth target still on track pending broader agreement on research standards for elephant-derived genomic data. Plans are also in place to add 30,000 square feet of avian research space for the moa and dodo programs; Lamm confirmed a moa revival will not occur in 2026.
