To determine if an IPv4 packet is carrying an ICMPv4 packet, you can examine the packet's protocol field in the IPv4 header. The protocol field specifies the type of payload the IPv4 packet carries, and for ICMPv4, this field is set to 1. Additionally, you can analyze the packet's structure; ICMPv4 packets have a specific format beginning with a type field that indicates the kind of ICMP message being transmitted.
IPv4 was described in RFC 791 in September 1981.
