palaeofail:Things don’t have to look anything like their ancestors, anatomy-wise!That was sarcasm. While organisms don’t necessarily have to look like their ancestors, birds and other small theropods share numerous anatomical features found in no other animals. Pterosaurs were by no means the ancestors of birds; they diverged from the lineage that produced birds about 80 MA or so before birds evolved. -- source link
