Unless it’s been burnt, nearly every plastic toothbrush ever made since the 30s is still out there somewhere. These were all picked up from Cornish beaches. #plasticheritage

Ice cream spoons. Used once and thrown away. These all washed ashore with seaweed from the seabed. They don't float. All from one beach. #plasticheritage

Toy animals of the Plasticene, all found on Cornish beaches. #contemporaryarchaeology #plasticheritage #Anthropocene

Micro beachcombing. #plasticheritage #plasticarchaeology

Feeling green. Beach finds including a Robin Hood figure given away in cereal packets in the 60s, a Pokemon lolly stick from 1999, plastic pegs and pop-up pirates' swords. #plasticheritage

Our beachcombed breakfast. Beachcombing in the Anthropocene. #plasticheritage

While mudlarks find bone and bronze hairpins, we beachcombers pick up plastic ones. #contemporaryarchaeology #plasticheritage

Archaeology of the jelly shoe buckle. From our Museum of Plastic in the Sand and Sea. Some of these are probably 40-50 years old. #plasticarchaeology #plasticheritage #contemporaryarchaeology #Anthropocene

Washed up mouse from the game Mousetrap, first published by Ideal in 1963. Not sure how old this particular mouse is but he's quite sea-worn. I wonder where he begun his journey to the sea, and how long ago. Mousetrap isn't a game you typically take to the beach. #plasticheritage

On the strandline this morning, this doll's head. Not sure how old it is - sixties maybe? Made in Hong Kong. #plasticheritage #contemporaryarchaeology

What will archaeologists of the future make of our plastic scatter, the billions of pieces we will leave behind - will they be able to identify them? Beachcombing in the Anthropocene. #plasticheritage #contemporaryarchaeology

This 45-year old bubble bath bottle/piggybank washed up in Cornwall yesterday. It was made in Canada in 1976. Where has it been all that time? Not buried in dunes as it's covered in algae. #plasticheritage

Tallon jet car from 1962, found on a Cornish beach. Washed out of the sand after a winter storm. Hours of fun for only a shilling. #plasticheritage

This Zorro ring was given away in packets of Quaker Puffed Wheat in 1959. Some 60 years later we found it on a Cornish beach, washed out of the sand after a storm. #plasticheritage #contemporaryarchaeology #Anthropocene

Hair slides/accessories found on Cornish beaches. Many are thought to be 'vintage' Goody barrettes from the 80s, though you can still buy them today. #plasticheritage #plasticarchaeology #contemporaryarchaeology #anthropocene

Reunited for #FindsFriday - Robin Hood and Maid Marian, both found on Cornish beaches just a few miles apart. These were free inside packets of Kellogg's cornflakes in the 60s. Thanks to beachcombing pal Alan Alder for the loan of Maid Marian for the occasion! #plasticheritage

Bag for life? An old Halfords plastic carrier bag we found washed out of the dunes after storms. A similar one spotted for sale online had a receipt inside from 1973. #plasticheritage #anthropocene #contemporaryarchaeology

These baking powder submarines were all found on Cornish beaches, washed up from the seabed after storms. Free in Kelloggs cereal packets, the orange one here is either from 1957 or 1963 and the yellow subs are from 1986. #plasticheritage

Found a jigsaw from 1956 that features the Noddy toothbrush we found washed up! Toothbrush placed on jigsaw for scale. How long they were produced for we're not sure. #plasticheritage #beachcombing #contemporaryarchaeology #anthropocene
