On the left side of the image, there is a map of the Pacific Ocean with a red line graph on the top left corner. The graph shows the number of primary producers in the region. The top right corner of the map shows a 3D model of a rock formation with a circular pattern on it. The bottom left corner shows a blue wave-like pattern, which appears to be a representation of the ocean floor. The image is accompanied by text that reads "Primary producers crash" and "The KPI boundary". On the bottom right corner, there are two smaller images, one of a person standing on a rock and the other of a group of people.</caption><transcript><audio_85>production uh exactly in the border as you can see here sorry and the symbol of this is the clay layer that we found almost in all the kpg</transcript><transcript><audio_86>powder in the whole world and this we found the clay because there is no a carbonate production and also we got a negative excursion of beta</transcript> in the atmosphere and sinks very fast and then we see this eye concentration in correlated to the eruption so during the the last 10 000 years of the cretaceous and we see a lot of eruption a lot of increase in uh in the mercury concentration which is also related to a very hot temperature and increasing the climate change and now we're working on this section on the all our section and we're working on the species that literally which is the kpg survival species and we try to collect its bloom to the mercury concentration but this is outside but whatever the main trigger for the environmental catastrophe is a bone theory the asteroid and the volcanism imply that the fold is on the primary producer actually the caused primary producer crashed that lead to the extension of all other groups i mean when the photosynthesis creatures are dead and there is no photosynthesis there's nothing to eat and all other creatures in the food chains are also dead and got extinct um so the um the evidence for this crash is the presence of a it's a reduction in calcite production uh exactly in the border as you can see here sorry and the symbol of this is the clay layer that we found almost in all the kpg powder in the whole world and this we found the clay because there is no a carbonate production and also we got a negative excursion of beta
