animal brawl part 1

it is in the middle of a sever drought that has been lasting for months now. animals are drooping like fies. there is only a few lakes left and one of them(the largest) is the closest. the lake stretches for almost a mile but is very shallow and only 15 feet deep at its lowest points.  a family of t.rexs is looking for water and soon they find the river and all began to drink. a unusuall herd of mammals consisting of a pack of dire wolf, smilodon, xenosmilus, and mastodon. they are brought together by a common enemy, drought. the herd is looking for water and soon they find refuge and began to drink as much as they can. there are crocodiles such as scrosuchus and deinosuchus in the river along with oxalia,spinosaurus,abd suchomimus. they are extremly agerresive for some reason and will kill anything they dont like wich unfortunetly happens to be everything. a pack of yangchuanosaurus,kelemayiasaurus,allosaurus,albertasaurus,and schaochilong all arrive at the same time. they were following the larger predators like this clan of giganotosaurus. a mile back is a murder of 13 mapusaurus. behind then is a pack of dilophosaurus. followed by two packs, one torvosaurus and the other sauruophaganax. they have known each other for a long time and have full respect for the other group. a trio of full grown argentinosaurus arrive on the seen and begin drinking. the rest of the herd never made it. behind them is a bachelor group of three acrocanthosaurus and a pack of inostrancevia. out of the mud comes the king of constictors, titanoboa. an ankylosaurus pair emerges from the field and behind them are four babies. there are also a large pack of titanis. a hatzegopterx soars over to the scene and also drinks, followed by a trio of tyranotitan.. there are many predators and prey here. all of them have another species at the river that they are mortal enemies with. as they all drink something happens and the tension breaks. a titanis attacks a inostrancevia and all hell breaks loose. what happend? the water had an infectious plankton that causes extreme agression in animals and irrational behavior.
