The Burgess Shale is not the sole record we have of a Cambrian soft-body deposit.

In this ...individual lobopods of E. rowelli proved far more diverse than previously thought and might be governed by a complex interplay of 15 muscles, including one promotor, one remotor, one levator, one retractor, two depressors, two rotators, one flexor and two constrictors as well as muscles for stabilization and haemolymph control.

Our planet has been many different worlds over its 4.5-billion-year history. Imagining what they were like is hard—with our limited lifespan, deep time eludes us by its very nature.
Insects gave the world flight, and flight gave them the world. Early-diverging lineages of Pterygota had wings with fixed, outstretched positions, their only extant descendants being today’s mayflies (Ephemeroptera), dragonflies, and damselflies (both Odonata). Subsequent modifications permitted flexion of the wings over the abdomen …6. Externally the segmentation is denoted only by the presence of short paired (14-13 pairs) un-jointed stumpy walking legs (lobopods). The legs are terminated into curved claws. 7. The head bears 3 paired appendages: (i) One pair fleshy annulated antennae (ii) A single pair of jaws (2nd pair of appendages) and
