| Growth protocol |
Embryonic mice (ICR strain, Taconic) and opossums were obtained from timed matings [1, 2] in breeding colonies housed in the Sears Lab at the University of Illinois. Pig embryos were obtained through timed inseminations following ovulations at the University of Illinois pig farm [3]. Bat embryos were obtained from field collections in Trinidad and staged according to Cretekos et al. 2005 [4].

total RNA |
| Extraction protocol |
Limbs were removed from embryos and stored in RNALater in -20° C until further processing. RNA was extracted from tissues using E.Z.N.A. Total RNA Kit I (OMEGA bio-tek #R6834), and converted into RNASeq libraries with the Illumina TruSeq RNA Sample Preparation Kit (Illumina RS-122-2001).
Libraries were sequenced on an Illumina HiSeq 2500 housed in the Roy G. Carver Biotechnology Center at the University of Illinois.

| Data processing |
Sequenced reads werepreprocessed to remove Illumina adaptors, and bases with qualities below 20 at the read's 3 prime end were trimmed. Reads from mouse, opossum, and pig were aligned using STAR (--outFilterMultimapNmax 10, --outFilterMismatchNmax 3, --outFilterScoreMin 0, --clip3pNbases 0, --clip5pNbases 0). Reads from bat were aligned using RSEM (--fragment-length-mean 425.0 --fragment-length-sd 150.0).
Gene expression (fragments per kilobase of transcript per million mapped reads, FPKM) were computed using cufflinks (for mouse, opossum, and pig) and RSEM (bat).
Genome_build: For mouse, opossum, and pig, we used their corresponding Ensembl reference genomes and annotation assemblies: GRCm38 (mouse), BROADO5 (opossum), and Sscrofa10.2 (pig). For bat reads, we used as a reference a de novo assembly. In short, we merged all libraries (from all stages) and called a de novo transcriptome using Trinity, then from the resulting de novo transcriptome we filtered out any sequence not matching the SwissProt database (blastx, e-value<1e-20).

Supplementary_files_format_and_content: *_genes.fpkm_tracking: Tab-delimited text files include CUFFLINKS gene expression (FPKM).
