It was that British show where animals from the past/future pop up in modern day times and cause havoc and there's rhis government agency that keeps the whole thing under wraps.

I watched it too

That show was great

You are certainly not, I accidentally clicked on it and got hooked. The ending of season one tho, it had me in tears.

It's been so long so the only thing that I remember from the season finale was the gorgonopsid-future predator fight.

I remember binging that for about maybe three seasons at most? It really took me for a spin on the later seasons.

I finished the series
